A STUDY SUBSONIC AND HYPERSONIC FLOW ON AN AIRFOIL

Abstract

First in this research I study's about (subsonic and hypersonic flows on an airfoil)which consists of three Chapters; Chapter one by the title: (Compressible Potential Flow)contains: Introduction, Speed of sound, Irrotational flow, :Linearized potential equation which includes Applications, Perturbation potentials), Pressure ) coefficient of small perturbations, Relation for subsonic compressible flow including (Airfoils (2-D flow), Boundary conditions, Pressure coefficients), .Critical Mach numberandSupercritical airfoils However, in Chapter two (Two-Dimential subsonic and supersonic equation) solution which of the includes: linearized Effects of .compressibility, Linearized theory In the Chapter threewith the title: (Small Disturbance Theory) includes: Centered Prandtel- Meyer rereflction,Wave Interactions, including: (Oblique shock reflected from a wall, Oblique shock intersection), Shock strengthening, .Supersonic flow over airfoils
