The lee-side computation of first order compressible flow about wing-body configurations. book was simulated for a circular wing-body combination with very low aspect ratio wings in the ‘+’ (plus) configuration at incompressible speeds.

Two 2D engineering level methods, the discrete vortex model (DVM) and free vortex model (FVM) methods were utilized to simulate the flow for three different. The wings in compressible flow, such as transonic flow, subcritical flow, supersonic linearized theory, and other aspects of supersonic wings are discussed in this chapter.

This book deals with numerical simulations and computations of the turbulent flow around high-lift configurations commonly used in aircraft. It is devoted to the Computational Fluids Dynamics (CFD) method using full Navier-Stokes solvers typically used in the simulation of.

Compressible Fluids Notes 1 1. Introduction Compressible Fluid Dynamics refers to fluid flow in which the velocity of the fluid motion is sufficient to “squeeze” and “stretch” the fluid, altering its density.

Thus, we can no longer use the incompressible assumption of constant density that was so essential in developing the relations of low velocity fluid dynamics (e.g.
