Abstract

In this paper, a single high-order compact flowfield-dependent variation (HOC-FDV) method is developed, valid for two�dimensional inviscid compressible as well as incompressible flow problems. The method has third-order accuracy in time and fourth�order accuracy in space. The FDV scheme is used for time dis�cretization and the fourth-order compact Pade scheme is used for spatial derivatives. The solution procedure consists of a number of tri-diagonal matrix operations and produces an accurate solver. Numerical examples are solved to demonstrate the accuracy and convergence characteristics of the high-resolution scheme. The test cases are flow over a compression corner, a channel flow with com�pression/expansion, and a flow past NACA 0012 airfoil. The numer�ical results show an excellent agreement with analytical and pub�lished numerical results and they clearly demonstrate the higher accuracy of a single HOC-FDV scheme for both incompressible and compressible flows.
