Kinetic theory for particles in dilute and dense solid-liquid flows

This paper presents a kinetic theory for modeling the vertical profile of p article concentration in dilute and dense solid-liquid flow conditions. The kinetic theory properly describes the mechanism of suspended sediment tran sport over a wider range of conditions and gives more detailed microscopic information than previous theories. Experimental data have been measured us ing laser Doppler anemometry. The results an in agreement with measurements by Wang and Qian in 1989, Michalik in 1973, and Segre and Silberberg in 19 62. The present work makes a special contribution in predicting the particl e concentration distribution in a dense liquid-particle flow with reasonabl e accuracy.
