基于CPU-GPU的超音速流场N-S方程数值模拟
Numerical Simulation of N-S Equations for Supersonic Flow Fields Based on CPU-GPU
摘要
Abstract
To thoroughly analyze the characteristics of supersonic flow fields and enhance the effi-ciency of numerical computations,an efficient acceleration algorithm was designed.The algorithm herein fully leveraged the CPU-GPU heterogeneous parallel architecture and achieved data transmission and pro-cessing through asynchronous streaming,significantly accelerating the computational processes of super-sonic flow field numerical simulations.The results demonstrate that the computational speed of GPU paral-lel processing is markedly faster than that of CPU serial processing,and the speedup ratio exhibits a pro-nounced increasing trend as the scale of the flow field grid expands.GPU parallel computing may effectively improve the computational speed of supersonic flow field simulations,providing a robust parallel computing method for the design,optimization,performance evaluation,and development of supersonic aircrafts.关键词
