Steady and unsteady transonic flow

16th Aerospace Sciences Meeting, 1978
An investigation of the transonic flow over a circular arc airfoil was conducted to obtain basic information for turbulence modeling of shock-induced separated flows and to verify numerical computer codes which are being developed to simulate such flows. The investigation included the employment of a laser velocimeter to obtain data concerning the mean

The Stabilization Law for Transonic Flow

SIAM Journal on Applied Mathematics, 1986
The stabilization law for transonic flow expresses the experimentally observed freezing of the local Mach number near the airfoil and ahead of the shock at free stream Mach numbers near one. Mathematically this means that near Mach one the flow over an airfoil is a small perturbation of sonic flow.

Transonic flow in unconventional nozzles.

AIAA Journal, 1968
The description of the compressible gas flow in the throat region of unconventional rocket nozzles must be known in order to optimize the wall contours and to predict the performance. The existence of both subsonic and supersonic flow in close proximity does not permit the use of conventional analytical techniques to obtain a mathematical description ...

Flow in Transonic Compressors

AIAA Journal, 1980
Introduction B the term transonic compressor we mean an axial flow compressor in which the inlet flow Mach number, relative to the rotating blades, varies from below unity at radii near the inner casing or hub to values substantially above unity at radii near the blade tips.

Gurney Flaps in Transonic Flows

2003
The 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 ...

MIXED EQUATIONS AND TRANSONIC FLOW

Journal of Hyperbolic Differential Equations, 2004
This paper reviews the present situation with existence and uniqueness theorems for mixed equations and their application to the problems of transonic flow. Some new problems are introduced and discussed. After a very brief discussion of time-dependent flows (Sec. 1) the steady state and its history is described in Sec. 2. In Secs.

Subsonic Potential Flow and the Transonic Controversy

SIAM Journal on Applied Mathematics, 1993
Summary: The two problems of a two-dimensional flow of an inviscid, compressible, perfect diatomic gas past a circular cylinder and past a sinusoidal wall are considered. It is shown that in both cases the coefficients of the maximum speed series can be interpreted as moments with positive weight on a finite support.
