Transonic flow is generally associated with the inviscid fluid effects when a flow with a freestream Mach number M ∞ ≃ 1 accelerates to locally supersonic velocities, or decelerates to locally subsonic velocities, as it moves streamwise past a body. However, transonic flows can occur in many other circumstances such as on high lift devices at low M ...

Non-isentropic potential formulation for transonic flows
21st Aerospace Sciences Meeting, 1983A potential equation for nonisentropic transonic flows is formulated. This procedure captures shock waves with Rankine-Hugoniot strengths, but retains the simplicity of the traditional potential equation. Numerical computations are presented that verify the efficiency of the present procedure. It is also shown that Crocco theorem [\textit{L. Crocco}, Z.

Transonic flow past lifting wings.
AIAA Journal, 1973Work conducted by Norstrud (1971) has been extended to lifting flows with the inclusion of embedded continuous supercritical regions. The approach taken follows some fundamental steps proposed for two-dimensional flows by Oswatitsch (1950). The governing integral equation is replaced by a system of nonlinear algebraic equations.

Summary: The structure of the flowfield in the vicinity of the trailing edge of a flat plane at zero incidence in mixed transonic flow has been studied using viscous-inviscid interaction methods. The resulting nonlinear partial differential equations governing the flow were solved numerically using finite-difference methods for a range of values of a ...

Mathematical Problems in Transonic Flow
Canadian Mathematical Bulletin, 1986AbstractWe present an outline of the problem of irrotational compressible flow past an airfoil at speeds that lie somewhere between those of the supersonic flight of the Concorde and the subsonic flight of commercial airlines. The problem is simplified and the important role of modifying the equations with physics terms is examined.

Gurney Flaps in Transonic Flows
2003The application of Gurney flaps to airfoils, high aspect ratio wings and delta wings in transonic flow is being investigated at the Institute of Aerodynamics and Flow Technology of DLR. The present paper gives an overview over these studies explaining the basic working principles and advantages of these trailing edge devices at transonic Mach numbers ...

Abstract The effect of viscosity on the relative motion of a fluid and a solid body or of two fluids finds its manifestation in the fluid stress whose two components, the shear stress and the longitudinal stress can usually be treated separately.

The paper is only a brief account of the most typical peculiarities of internal transonic flows rather than any detailed report on any particular problem. The reason for this general orientation of the paper is in my belief that while there are at our disposal many highly efficient computing facilities and sophisticated codes capable of solving almost ...

Abstract Although the theory of a steady transonic flow, as given in Chapter 2, is well suited for computations of transonic flow fields, the reason for the much quoted “sound-barrier”—that is, the strong increase in drag of a flying object at its approach to the velocity of sound—is not obvious from those theoretical studies.
