An approximation that can be used to determine how swirl affects the choking constraint on flow through the throat of a nozzle is obtained. The flow model is consistent with an experimentally observed flow pattern that contains a recirculating internal cell upstream of the throat.

The simulation of unsteady transonic flow and the stability of a transonic boundary layer
Journal of Applied Mathematics and Mechanics, 2005The authors discuss modification of a model (see \textit{O. S. Ryzhov} [Sov. Phys. Dokl. 22(1977), 537--539 (1978; Zbl 0359.76036)]) for investigation of free nonstationary visco-nonviscous interaction at transonic velocities. The model modification consists in taking into account a singular term of transonic extension and allows to refine the Lin ...

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.

ROBUST NUMERICAL METHODS FOR TRANSONIC FLOWS
International Journal for Numerical Methods in Fluids, 1997Summary: We discuss numerical methods for solving the transonic full potential equation. The governing equation is discretized by a flux-biasing finite volume method. The resulting nonlinear algebraic system is solved by using a continuation method with full Newton iteration.

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 ...
