On a Computational Method for Impact of Compressible Fluid

Abstract

The initial stage of a compressible liquid jet impact onto an elastic plate is considered in the paper. A numerical model is built and the wave governing equation is approximated by a doubly asymptotic method. Theoretical solution at the impact instant is deduced through considering compressibility or not. Doubly approximation method is compared with the analytic solution by Korobkin and theoretical solution respectively, showing that this approximation method is efficient and accurate.
