Traditional boundary force method of SPH applies Lennard-Jones equation to compute the virtual repulsive force by calculation of molecular force. But this method is strongly non-linear and easily leads to not convergence in calculation. In this paper, spring-damping boundary force model is utilized to solve the problem of moving boundary. Using spring-damping boundary force model, rotary moving boundary of screw channel-driven has been simulated and the result is well consistent with the simulation of Fluent. Comparing with traditional boundary force equation, this model is long-term stable and its effectiveness has been validated by case study.
