Numerical simulation of Poiseuille flow based on moving particle semi-implicit method

Zhongguo Jianchuan Yanjiu, 2022
ObjectivesPoiseuille flow widely exists in the industry, but the stability and reliability of the moving particle semi-implicit (MPS) method in the simulation of wall shear flow such as Poiseuille flow need to be verified.
