Solutions of the Euler Equations for Flows over Configurations at High Angles of Attack

Abstract

Given the greater efficiency of algorithms, coupled with ever-faster computers with increased memory capacity, it is becoming more practical to calculate flow over complex configurations using direct solutions of the differential equations (Euler equations for inviscid flows, Navier-Stokes for viscous flows) representing mass, momentum and energy conservation laws. The solutions must comply with the appropriate initial and boundary conditions. The availability of large vector computers has enabled researchers to attempt the modeling of increasingly more complex geometries and the calculation of flow at higher angles of attack by solving Euler or Navier-Stokes equations. The recent development of parallel computers may facilitate further increases in the speed and complexity of such calculations. This chapter will be devoted to the discussion of the methods of solving Euler equations and their application to studies of flows at high angles of attack. The solutions of the Navier-Stokes equations and their application to computations of high angles of attack flows will be discussed in Chapter 9.
