The experimental information that can be gained from this infrastructure would lead to significant advances in understanding turbulent flows, which would impact a broad range of engineering and geophysical fields. Some specific examples include the development of efficient turbulence control strategies for the reduction of skin-friction drag and improved combustion processes, resulting in not only better fuel efficiency for vehicles but also reduced CO2 and pollutant emissions. Significant advances could also be made in the area of understanding the dispersion of particles, including pollutants, in the atmosphere; wind turbine design and implementation strategies, and climate change modelling.Read moreRead less
Turbulent mixing of a passive scalar. Turbulence is the usual state of fluid motion.

Surface roughness and its effects on wall-bounded turbulence. Examples in engineering where turbulence is important are: wind tunnel model testing, numerical prediction of turbulent skin friction drag over an aircraft wing, turbulent forces and acoustic field around a submarine or a road vehicle, and the dispersion of pollutants in the atmosphere. Turbulence may also be beneficial, for example, in improving engine combustion and decreasing pollutant emissions. Hence this study will have national ....Surface roughness and its effects on wall-bounded turbulence.
