摘要：
A new model of particle yield stress including cohesive strength is proposed, which considers the friction and cohesive strength between particles. A calculation method for the fluidization process of liquid-solid two-phase flow in compact packing state is given, and the simulation and experimental studies of fluidization process are carried out by taking the sand-water two-phase flow in the jet dredging system as an example, and the calculation method is verified.
