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.

Modern Developments in Transonic Flow
SIAM Journal on Applied Mathematics, 1975A survey is given of transonic small disturbance theory. Basic equations, shock relations, similarity laves, lift and drag integrals are derived., The airfoil boundary value problem is formulated. Finite difference methods and computational algorithms are described. Results are compared with other calculation methods and experiments.

Transonic flow about lifting configurations.
AIAA Journal, 1973A transonic flow solution is presented for configurations with span-to-length ratios of order one. The angles of attack are sufficiently large to produce lift effects that are either dominant or comparable to the thickness effects. The analysis is performed with the aid of the method of matched asymptotic expansions.

15th AIAA Computational Fluid Dynamics Conference, 2001
Unsteady flow over shallow cavities (L/D = 4 and L/D = 8) at Mach = 0.8 is investigated experimentally. Data acquisition in and above two-dimensional rectangular cavities is accomplished optically via a multiple exposed Shack Hartman sensor. This technique provides a time-accurate picture of the density behavior in and above the cavity without the need

Transonic swirling nozzle flow
27th Joint Propulsion Conference, 1991A numerical model of viscous transonic swirling flow in axisymmetric nozzles is developed. MacCormack's implicit Gauss-Seidel method is applied to the thin-layer Navier-Stokes equations in transformed coordinates. Numerical results are compared with experimental data to validate the method.

Some degenerate transonic flows
Journal of Applied Mathematics and Mechanics, 1958Abstract We consider transonic motions of an ideal gas which are represented in the velocity hodograph by a curve or by a surface. In the second part of the note we determine a class of self-similar solutions representing plane and axially symmetric flows.
