Description

In the period of December 1, 1991 to February 28, 1992 further progress 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. A stress transport model for rapid granular flows in a rotating frame of reference was formulated. The thermodynamically consistent constitutive equations were derived. It was shown that the model contains the existing kinetic theories as special limiting cases. The model predictions for the special case of rapid simple shear flows were compared with … continued below

Description

In the period of December 1, 1991 to February 28, 1992 further progress 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. A stress transport model for rapid granular flows in a rotating frame of reference was formulated. The thermodynamically consistent constitutive equations were derived. It was shown that the model contains the existing kinetic theories as special limiting cases. The model predictions for the special case of rapid simple shear flows were compared with the available simulation data. The kinetic model for rapid flows of granular materials, which includes frictional losses, was used for studying several parallel shear flows. These include Couette and gravity flows. Progress has been made in developing a computational model for rapid granular flows in complex geometries. The design for the experimental simple shear flow device was also improved, and the construction of the device was initiated.
