MIXED EQUATIONS AND TRANSONIC FLOW
Journal of Hyperbolic Differential Equations, 2004This 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.

The shape of a liquid bell resulting from the overflow of a viscous liquid out of a circular dish is investigated experimentally and theoretically. The main property of this bell is its ability to sustain the presence of a “transonic point,” where the liquid velocity equals the speed of antisymmetric—or sinuous—surface waves. Their shape and properties

As the air flow around an aircraft is not uniform, locally supersonic zones may exist even under subsonic upstream flow condition, this defines the transonic regime, a condition where both subsonic and supersonic regions coexist.

FEM is here used to ascertain the stability and aeroelastic response of thin, 2D panels subjected to Mach 0.8-2.5 flows. In the absence of shocks, it is found that the Euler equations used to represent the unsteady flowfield dynamics predict response behaviors resembling those obtained via potential flow methods. Where shocks do play a significant role

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.

1973Abstract : The problem to which work reported addressed itself is, briefly, how can one predict the aerodynamic characteristics of airfoils at transonic speeds simply while at the same time including the effects of fluid viscosity.

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.
