Abstract

In different flow fields, the description and tracking of droplets in computer has high time complexity. In order to improve the efficiency of droplet simulation and calculation, on the domestic DCU acceleration device, the immersed boundary methods is used to realize the simulation of droplet deformation under shear flow. After finite difference of the hot spot pressure Poisson equation, the Jacobian implicit iterative method is used for parallel improvement, divide a larger computing task into multiple independent computing modules, and make reasonable use of the local data share to reduce the number of global memory accesses. The results show that compared to the CPU serial implementation, The heterogeneous droplet deformation simulation achieved the highest speedup ratio of 2.34 under the premise of ensuring accuracy.
