Flux splitting is the main method to realize the upwind characteristics under the condition of equations. In order to realize the performance analysis of typical flux splitting formats on CPU/GPU heterogeneous platforms. On NVIDIA GTX1660super, a one-dimensional Euler solver is implemented using the Compute Unified Device Architecture (CUDA) programming model. Taking the Riemann problem of shock tube as an example, van Leer, Roe and AUSMPW + are calculated and analyzed in vector flux splitting scheme, flux differential splitting scheme and mixed flux splitting scheme. The numerical results show that the three schemes can get reasonable and usable results in the heterogeneous computing system. Roe format has the highest resolution and the best acceleration effect in CPU/GPU system. The resolution of Van Leer shock wave is lower than Roe and AUSMPW+, and the calculation efficiency is high. However, there are a lot of judgment branches in the structure of Van Leer shock wave, which affects the acceleration performance. The AUSMPW+ format has a shock resolution comparable to Roe and a slightly better acceleration performance than Van Leer.
