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.

Analysis of nonlinear transonic blockage in unsteady transonic flows
28th Fluid Dynamics Conference, 1997Numerical simulation of the oscillation of strong to weak shocks in a Laval nozzle, due to downstream static pressure sinusoidal fluctuations, is presented. The strong shock motion is mainly harmonic. However, static pressure signals, recorded near the shock/boundary layer interaction and on the axis downstream of the shock, show several higher modes ...

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.

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.

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 ...

A predominantly experimental investigation into the nature of transonic flow within an aerodynamic corner is treated. The work focuses on exploring the shock-induced separation that can occur due to the corner. Effects of dihedral angle, and sharp and filleted 90º corners were studied on a RAE2822 profile wing.
