A computational model for coal transport and combustion. Quarterly technical progress report, September 1--November 30, 1991
During the last three months, considerable progress has been made in formulation of the thermodynamically consistent rate dependent model for turbulent two-phase flows. The basic governing equations were derived and the case of a simple shear flow was also analyzed. Preliminary comparisons with the available experimental data were also performed. The thermodynamical approach was successfully formulated for developing a stress transport model for granular flows. The appropriate constitutive equations were derived and it was shown that the model contains the existing kinetic theory results as special limiting cases. The formulation also allows for the possible rotation of the frame of reference. Using a kinetic-based model which includes frictional losses, several rapid granular shear flows including Couette and gravity flows were analyzed. Preliminary comparisons with experimental data were also performed. The experimental setup for the simple shear flow device is being designed. The procedure for constructing the device is being studied.
