Description

In the period of December 1, 1993 to February 28, 1994, considerable progress in the experimental study of monogranular layer simple shear flow device was made. Experimental data concerning the mean granular velocity, fluctuation velocity and solid volume fraction were obtained. The resulting data revealed new interesting features of particulate flows. The thermodynamically consistent, rate dependent model for turbulent two-phase flows and its application to analysis of simple shear flow was completed. Further progress on the application of the kinetic model for rapid flows of granular materials including the frictional energy losses were made. The flow over a vibrating plate … continued below

Description

In the period of December 1, 1993 to February 28, 1994, considerable progress in the experimental study of monogranular layer simple shear flow device was made. Experimental data concerning the mean granular velocity, fluctuation velocity and solid volume fraction were obtained. The resulting data revealed new interesting features of particulate flows. The thermodynamically consistent, rate dependent model for turbulent two-phase flows and its application to analysis of simple shear flow was completed. Further progress on the application of the kinetic model for rapid flows of granular materials including the frictional energy losses were made. The flow over a vibrating plate was analyzed and the velocity, the fluctuation energy and the solid volume fraction profiles were evaluated. A computational model for analyzing flow of granular materials in ducts and passages with bumpy walls was developed. The special cases of Couette and chute flows was analyzed. The results were compared with the experimental data and good agreement was observed. Flows of gas-solid mixtures in vertical ducts were studied. A computational model for analyzing two-phase flow was developed, and the phasic mean velocity and fluctuation energy profiles were evaluated.
