Aerodynamic force by Lamb vector integrals in compressible flow
, 2014A new exact expression of the aerodynamic force acting on a body in steady high Reynolds number (laminar and turbulent) compressible flow is proposed. The aerodynamic force is obtained by integration of the Lamb vector field given by the cross product of

Introduction Chapters 10 and 11 address flows in which substantial changes in density occur. The changes arise from processes which are dynamical (e.g. density changes from pressure variations associated with fluid accelerations) or thermodynamic (density changes primarily from bulk heat addition due to chemical reaction or phase change) or a ...

AbstractHelical (Beltrami) flow with nonuniform coefficient is considered for the case of compressible fluid and a class of exact solutions is proposed. A paradox of helical flow is discussed and the compressibility is considered as a possible resolution of the paradox. Examples with different symmetries are given for the compressible helical flow and,

When the density change of fluid is small (ρ1/ρ2 < 2) and the velocity not too high (Mach number, Ma < 0.3), then the mechanical energy balance reduces to the forms developed in Chapter 2. These equations represent the flow of all liquids as well as relatively slow moving gases. This is called incompressible flow.

In previous chapters we introduced and analyzed the discontinuous Galerkin method (DGM) for the numerical solution of several scalar equations. However, many practical problems are described by systems of partial differential equations. In the second part of this book, we present the application of the DGM to solving compressible flow problems.

In this chapter computational algorithms will be considered for solving flows governed by the full compressible Navier-Stokes equations, i.e. unsteady flow or flows with large areas of separation. Steady compressible viscous flows with a dominant flow direction and only small regions of separation can be handled with the techniques described in Chap ...

The viscous compressible flow in the vicinity of a right-angle corner, formed by the intersection of two perpendicular flat plates and aligned with the free stream, is investigated. In the absence of viscous-inviscid interactions and imbedded shock waves, a theory is developed that is valid throughout the subsonic and supersonic Mach number range ...
