The thermodynamically consistent rate dependent model for turbulent how of dense two phase solid-liquid mixtures derived previously is extended to cover the entire range of solids volume fraction. The modifications needed for the phasic viscosity, as well as the particulate energy dissipation rate, are included. It is shown that the model contains the existing kinetic models for rapid granular flows and dilute turbulent two phase flows as special limiting cases. The model is then used to study the problem of simple shear flow of a two phase solid-liquid mixture. The phasic shear and normal stresses, normal stress differences, fluctuation kinetic energy, production, dissipation and interaction energy supply are evaluated and discussed. The predicted stresses are compared with experimental data and good agreement is observed.
