Description

In the period of March 1, 1992 to May 30, 1992 considerable progress has been made in the development of the stress transport model for rapid granular flows in a rotating frame of reference. The derivation of thermodynamically consistent constitutive equations were complete. It was shown that the model contains the existing kinetics theories as special limiting cases. The model predictions for the special case of rapid simple shear flows were evaluated and the results are compared with the simulation data. Progress also has been made in formulation of the thermodynamically consistent rate dependent model for turbulent two-phase flows. The … continued below

Description

In the period of March 1, 1992 to May 30, 1992 considerable progress has been made in the development of the stress transport model for rapid granular flows in a rotating frame of reference. The derivation of thermodynamically consistent constitutive equations were complete. It was shown that the model contains the existing kinetics theories as special limiting cases. The model predictions for the special case of rapid simple shear flows were evaluated and the results are compared with the simulation data. Progress also has been made in formulation of the thermodynamically consistent rate dependent model for turbulent two-phase flows. The thermodynamically admissible constitutive equations were derived, and the case of a simple shear flow was also studied. The kinetic model for rapid flows of granular materials, which includes frictional losses, was used and the special case of gravity flows down an inclined chute was studied. The computational modeling for rapid granular flows in complex geometries was further developed. The design for the experimental simple shear flow device was further improved, and the construction of the device has started.
