Heatline Visualization of Natural Convection in a Porous Cavity Occupied by a Fluid With Temperature-Dependent Viscosity

DOI: 10.1115/1.2780179

Abstract: Temperature-dependent viscosity effect in buoyancy driven flow of a gas or a liquid in an enclosure filled with a porous medium is studied numerically based on the general model of momentum transfer in a porous medium. The exponential form of viscosity-temperature relation is applied to examine three cases of viscosity-temperature relation: constant, decreasing, and increasing. Application of arithmetic and harmonic mean values of the viscosity is also investigated for their ability to represent the Nusselt number versus the effective Rayleigh number. Heat lines are illustrated for a more comprehensive investigation of the problem.

Investigating the use of methane as diesel fuel in off-road haul road truck operations

Publisher: ASME International

Date: 04-08-2009

DOI: 10.1115/1.3185350

Abstract: A scope study is conducted to investigate the technical and commercial feasibility of converting existing mine haul truck engines to a fuel regime of methane and diesel. A dual fuel engine with two technology options of homogeneous gas charge and high pressure direct injection are considered. The results of this study show that cost reduction is only possible when methane is available at a cost saving that compensates for the expense of building a new fuel infrastructure, and a clean combustion is expected. In contrast to diesel-only engines, particulate emissions in dual fuel engines are less. However, unburned methane in the exhaust gases or significant methane leakage must be seriously taken into consideration for replacing diesel with methane. This scope study argues that the dual fuel operation with HGC/CNG technology is expected to be feasible even at a relatively small truck fleet size.

Longwall shearer cutting force estimation

Publisher: ASME International

Date: 19-02-2014

DOI: 10.1115/1.4026326

Abstract: Longwall mining is an underground coal mining method that is widely used. A shearer traverses the coal panel to cut coal that falls to a conveyor. Operation of the longwall can benefit from knowledge of the cutting forces at the coal/shearer interface, particularly in detecting pick failures and to determine when the shearer may be cutting outside of the coal seam. It is not possible to reliably measure the cutting forces directly. This paper develops a method to estimate the cutting forces from indirect measurements that are practical to make. The structure of the estimator is an extended Kalman filter with augmented states whose associated dynamics encode the character of the cutting forces. The methodology is demonstrated using a simulation of a longwall shearer and the results suggest this is a viable approach for estimating the cutting forces. The contributions of the paper are a formulation of the problem that includes: the development of a dynamic model of the longwall shearer that is suitable for forcing input estimation, the identification of practicable measurements that could be made for implementation and, by numerical simulation, verification of the efficacy of the approach. Inter alia, the paper illustrates the importance of considering the internal model principle of control theory when designing an augmented-state Kalman filter for input estimation.
