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 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 ...

Solid surfaces in like actuators, fluid mechanical models and surrounding walls can influence the fluid flow and/or can be deformed or displaced by it. The knowledge of the actual surface shape and location is therefore important for many fluid mechanical investigations.

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.
