Abstract
In order to solve the numerical method of nonconservative ideal hydrodynamics equations, the viscous perturbation technique for solving nonconservative hydrodynamics equations is improved and tested by solving the Riemann problem. The calculation of nonconservative ideal fluid mechanics is based on the GRP format. This article aims at the calculation method of nonconservative ideal fluid mechanics in the GRP format. Riemann and the corresponding periodic vortex are processed. The multifluid network processing method in the article is compared with the current method. The result can prove that this format can be used to solve the nonconservative ideal fluid dynamics equation of multiple values in the GRP format group, its computing power is strong, and the result of the solution is accurate.
Highlights
Relying on the multifluid grid parallel computing method can indicate the process of computing the GRP. e algorithm can be used to complete the traditional computing tasks that can be completed on a large computer or even a supercomputer on a PC or HPC composed of multiple GRPs
It can be seen that the numerical value obtained by using this type of scheme to solve the nonconservative equations of the GRP scheme is more unreasonable than that obtained by using the conservative GRP scheme to solve the nonconservative ideal hydrodynamics [4,5,6]
Aiming at the problem of low efficiency in the numerical calculation of nonconservative ideal hydrodynamics equations, this paper discretizes the values by using parallel calculation algorithm; that is, it is transformed into the GRP format and unstructured grid storage method. e combination of interpolation and reconstruction is used to ensure that the accuracy of the space is improved to the second stage
