Inviscid Compressible Flow in Meridional Plane of an Axial Flow Compressor
author
Abstract:
In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and radial components of the calculated blade force are added to the right hand side of the axial and radial momentum equation. By application of a 4th order Runge-Kutta time marching technique to the resulting 2-D Euler equations, the flow field is solved. Some interesting results are obtained which show the program capability in solving flow in the meridional plane of a compressor at the shortest possible time.

An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters to improve the order of accuracy and the two-layer Baldwin-Lomax turbulence model was also implemented. Two test cases were prepared to validate the solver. The computed results were compared with the e...
full textInstabilities of Stationary Inviscid Compressible Flow around an Airfoil
In this paper we numerically solve the stationary inviscid flow around an airfoil. Using the second-order explicit Runge–Kutta method in combination with the MUSCL scheme and the minmod limiter, we do not obtain a machine accurate solution. This has already been observed in literature and is explained by the non-differentiability of the minmod limiter. An analysis of the limiter shows that it i...
