提出了一种基于GPU的粒子方法在三维不可压缩粘性流体流动问题中的应用。粒子方法基于MPS（Moving Particle Semi-implicit）格式，利用基于GPU的SCG（Scaled Conjugate Gradient）方法，利用对数加权函数稳定泊松方程关于压力场的伪振荡解。数值结果通过对带旋转叶片的液环泵的溃坝湍流问题和湍流特性的分析，验证了本文方法的可行性和有效性。
: The application of a GPU-based particle method to three-dimensional incompressible viscous fluid flow problems is presented. The particle approach is based on the MPS (Moving Particle Semi-implicit) scheme using logarithmic weighting function to stabilize the spurious oscillatory solutions for solving the Poisson equation with respect to the pressure fields by using GPU-based SCG (Scaled Conjugate Gradient) method. Numerical results demonstrate the workability and the validity of the present approach through the dam-breaking flow problem and flow behavior in a liquid ring pump with rotating impeller blades.
