Unsteady Transonic Flows in an Axial Flow Compressor*
Introduction. This paper deals with some transonic flow problems for the supersonic axial flow compressor: these arise in connection with flutter analysis for fan blading. Very detailed solutions for unsteady plane transonic flows through a cascade of flat plates have been given by Goldstein Braun and Adamczyk (1977) and Nagashima and Whitehead (1977), see also Goldstein (1975), Kurosaka (1974)...
متن کاملPerformance Prediction Modeling of Axial-Flow Compressor by Flow Equations
Design models of multi- stage, axial flow compressor are developed for gas turbine engines. Axial flow compressor is one of the most important parts of gas turbine units. Therefore, its design and performance prediction are very important. One-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. In this appro...
متن کاملInviscid Compressible Flow in Meridional Plane of an Axial Flow Compressor
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 r...
متن کاملDesign and simulation of flow through subsonic axial compressor
Abstract―This paper illustrates the theory behind computational fluid dynamics (CFD) of flow though a gas turbine engine low pressure compressor. The goal of study is to develop a tool to perform shape optimization of low speed airfoils. Mathematical model and computational tool are developed using programming software. Analytical solution is developed to create airfoil geometry. The NACA 4 dig...
