Abstract

In this paper, the inviscid and viscous ultrasonic flow field of a Steam turbine blade with Denton method is investigated. The novelty of this paper is, improving Denton's finite volume method by adding the turbulence viscous term on 2-D modeling. This is an area that better understanding can lead to improved design. The unsteady Navier-Stokes equations govern the overall behavior of compressible Viscous flow and treated by the time marching scheme. For simulation in FORTRAN is used the finite volume method for discrete and Baldwin-Lomax model for the effects of turbulence in Viscous flow. Independency of the number of grid points are obtained. Pressure distribution has been validated with experimental data and on the Shock zone show good correlation and reduction of numerical errors with experimental data.
