Abstract

A higher-order accurate Navier-Stokes solver for simulating transonic ant supersonic flows in turbomachinery is presented. In this solver, a compact MUSCL TVD finite-difference scheme proposed by the authors which has fourth-order accuracy in space and second-order accuracy in time is used. The distinctive advantages of using the scheme art first that the shock resolution is superior than the existing TVD scheme which has at most second(third)-order accuracy in space, and that the present scheme enable us to simulate weak discontinuities such as slip tines as well as shocks completely and furthermore unsteady vortices more clearly in spite of simpler algorithm than so-called ENO scheme. Finally by using the present solver, steady and unsteady cascade flows with shocks, vortices and their interactions can simulate, more accurately than the existing Navier-Stokes solver for turbomachinery.
