Effects of manikin model simplification on CFD predictions of thermal flow field around human bodies
Publisher: SAGE Publications
Date: 07-06-2017
Abstract: Simplified computational thermal manikins are beneficial to the computational efficiency of computational fluid dynamics simulations. However, the criterion of how to simplify a computational thermal manikin is still absent. In this study, three simplified computational thermal manikins (CTMs 2, 3 and 4) were rebuilt based on a detailed 3D scanned manikin (CTM 1) using different simplification approaches. Computational fluid dynamics computations of the human thermal plume in a quiescent indoor environment were conducted. The predicted airflow field using CTM 1 agreed well with the experimental observations from the literature. Although the simplified computational thermal manikins did not significantly affect the airflow predictions in the bulk regions, they strongly influenced the predicted airflow patterns near the computational thermal manikins. The predictive error of the computational thermal manikin was strongly related to the simplification approach. The computational thermal manikins generated from the surface-smoothing approach (CTM 2) was very close to CTM 1, while the required mesh elements for a stable numerical solution dropped by over 75%. Comparatively, the predictive errors of CTMs 3 and 4 were considerable in the near-body regions. This study has illustrated the importance of keeping the key body features when simplifying a computational thermal manikin. The surface-smoothing-based simplification method was shown to be a promising approach.

A computational fluid dynamics study on the effects of computer fan on indoor airflow and indoor air quality in breathing zone
Publisher: SAGE Publications
Date: 14-11-2015
Abstract: Although desktop computers have been considered in many computational fluid dynamics (CFD) indoor simulations, they were usually simplified as hot boxes. A real desktop computer, however, is not only a heat source but also a momentum source due to the jet airflow generated by the computer case fan. The airflow induced by a desktop case fan could have the same order of magnitude as the ventilation rate of the whole room, and thus is expected to have significant influence upon the indoor airflow field and distribution of contaminants. Obviously, the simplification of desktop computer into a hot box does not sufficiently stand for the actual situation. In this study, a CFD model of a typical office room was built and simulations were conducted to investigate the airflow field and volatile organic compounds (VOC) distribution under two scenarios: (1) computer as a ‘hot box’ without a fan and (2) a more realistic computer model with an operating case fan. The comparison of CFD results yielded from these two scenarios demonstrated that the role of computer fan is very important in terms of airflow field and contaminant distribution and should be included in CFD office simulations for the purpose of improved reliability.
Flow boiling heat transfer of liquid nitrogen in heated u-tubes
Publisher: ASME International
Date: 07-11-2014
DOI: 10.1115/1.4025542
Abstract: The flow boiling heat transfer characteristics of liquid nitrogen in three U-tubes with different curvature ratios were investigated experimentally. The effects of inlet pressure, heat flux, and curvature ratio on heat transfer characteristic are analyzed. The results indicate that the local heat transfer characteristics change obviously as fluid flows through the return bend, especially in the case of high heat flux. The drying out occurs near the inner wall of the return bend under high heat flux. A parameter Rh (down/up), which is defined as the ratio of heat transfer coefficient between the downstream and upstream section of U-bend, is proposed to evaluate the contributions of the curvature ratio to the heat transfer. It is found that the Rh (down/up) increases with the decrease of the curvature ratios. Furthermore, the experiments results of the average heat transfer coefficient are compared with the calculated results of the empirical correlations.

Effects of cough-jet on airflow and contaminant transport in an airliner cabin section
Publisher: SAGE Publications
Date: 07-12-2018
Abstract: The goals of this study were to investigate the effect of cough-jet on local airflow and contaminant transport in a typical cabin environment by using computational fluid dynamics. A fully occupied airliner cabin section was employed as the computational domain. Contaminants were released through coughing passengers from different locations inside the cabin. Numerical results in terms of contaminant transport characteristics were examined and compared. It can be concluded that cough-jet has significant effects on air flow in front of cough passenger in a short period of time. Also, it was found that, without considering the cough-jet model, the simulation results could not be a precise representation of the transport and distribution of cough-generated airborne contaminants.

Southwest Australia Seismic Network (SWAN): Recording Earthquakes in Australia’s Most Active Seismic Zone
Publisher: Seismological Society of America (SSA)
Date: 18-01-2023
DOI: 10.1785/0220220323
Abstract: The geological structure of southwest Australia comprises a rich, complex record of Precambrian cratonization and Phanerozoic continental breakup. Despite the stable continental cratonic geologic history, over the past five decades the southwest of Western Australia has been the most seismically active region in continental Australia, though the reason for this activity is not yet well understood. The Southwest Australia Seismic Network (SWAN) is a temporary broadband network of 27 stations that was designed to both record local earthquakes for seismic hazard applications and provide the opportunity to dramatically improve the rendering of 3D seismic structure in the crust and mantle lithosphere. Such seismic data are essential for better characterization of the location, depth, and attenuation of the regional earthquakes, and hence understanding of earthquake hazard. During the deployment of these 27 broadband instruments, a significant earthquake swarm occurred that included three earthquakes of local magnitude 4.0 and larger, and the network was supplemented by an additional six short-term nodal seismometers at 10 separate sites in early 2022, as a rapid deployment to monitor this swarm activity. The SWAN experiment has been continuously recording since late 2020 and will continue into 2023. These data are archived at the International Federation of Digital Seismograph Networks (FDSN) - recognized Australian Passive Seismic (AusPass) Data center under network code 2P and will be publicly available in 2025.
Numerical investigation of micron particle inhalation by standing thermal manikins in horizontal airflows
Publisher: SAGE Publications
Date: 11-09-2014
Abstract: Computational fluid dynamics computations were conducted to investigate the particle inhalation characteristics of a thermal manikin standing in a horizontal airflow with different orientations, leg postures, wind speeds and particle sizes. The computations revealed that only when the manikin’s thermal plume moves into the breathing zone (namely, the manikin is facing the lee side) could the body heat affect the characteristics of particle inhalation. Further computations demonstrated that, when facing the lee side, the manikin’s particle inhalation is highly sensitive to its leg posture. When the legs are separated, air can flow through the gap, causing more particle entrainment into the breathing zone from the lower level. Although the thermal effect of body heat is gradually suppressed with increasing wind speed or particle size, different leg postures have different environmental sensitivities.

Source and trajectories of inhaled particles from a surrounding environment and its deposition in the respiratory airway
Publisher: Informa UK Limited

DOI: 10.3109/08958378.2013.781250
Abstract: The inhalation exposure to airborne particles is investigated using a newly developed computational model that integrates the human respiratory airway with a human mannequin and at an enclosed room environment. Three free-stream air flow velocities (0.05, 0.20, and 0.35 m s⁻¹) that are in the range of occupational environments are used. Particles are released from different upstream locations and their trajectories are shown, which revealed that the trajectory paths of 80 μm particles that are inhaled are the same from the three different upstream planes evaluated. Smaller particles, 1 and 10 μm, exhibited different inhalation paths when released from different upstream distances. The free-stream velocity also has an effect on the particle trajectory particularly for larger particles. The aspiration efficiency for an extended range of particle sizes was evaluated. Reverse particle tracking matches the deposition in the respiratory airway with its initial particle source location. This can allow better risk assessments, and dosimetry determination due to inhalation exposure to contaminant sources.

DOI: 10.7867/1983-1501.2018V20N2P62-76
Abstract: O uso de tecnologias para redução da evaporação de reservatórios pode ajudar regiões áridas e semiáridas a superar a escassez hídrica. Alguns mecanismos, como filmes monomoleculares e estruturas flutuantes, podem apresentar efeitos negativos nos ambientes aquáticos e na qualidade da água. Este trabalho investigou a eficácia de três mecanismos de redução de evaporação que possuem alto desempenho ambiental: coberturas suspensas, destratificadores e quebra-ventos. A análise foi conduzida com o modelo DYRESM em um reservatório localizado no sudeste do estado de Queensland, Austrália. O modelo foi primeiramente calibrado e validado para o reservatório em estudo. Em seguida, as condições de contorno foram alteradas para refletir os efeitos dos mecanismos de redução de evaporação no comportamento térmico do reservatório. O método mais eficaz foi o uso de coberturas suspensas, que reduziu em 88% a evaporação. O uso de quebra-ventos reduziu em 27% a evaporação, e o uso de destratificadores não teve efeito significativo na redução da evaporação. Para cada um dos mecanismos estudados, uma análise compreensiva dos seus efeitos na temperatura da água e nas taxas de evaporação foi efetuada, inferindo sobre os potenciais resultados do uso destes mecanismos em reservatórios de outras condições climáticas.
