Abstract

This research describes the development of a new structured 2D CFD solver for compressible flow. The high-speed turbulent flow in a diffuser and a cascade of nozzle blade are predicted using standard k-e turbulence model. The new finite volume CFD solver employs second order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta time integration to solve the set of non-linear governing equations with variables stored at the vertices. Artificial dissipations with pressure sensors are introduced to control solution stability and capture shock discontinuity. In general, the predictions compare well with the experimental measurements.
