Subsonic Potential Flow and the Transonic Controversy
SIAM Journal on Applied Mathematics, 1993Summary: The two problems of a two-dimensional flow of an inviscid, compressible, perfect diatomic gas past a circular cylinder and past a sinusoidal wall are considered. It is shown that in both cases the coefficients of the maximum speed series can be interpreted as moments with positive weight on a finite support.

OPtimum design for potential flows
International Journal for Numerical Methods in Fluids, 1983AbstractDescribed in this paper is a methodology for solving a particular class of optimum design problems in Fluid Mechanics, namely optimum design problems for aerofoils when the corresponding fluid flow is potential. The methods described in this paper operate directly in the physical space, and take advantage of the variational formulation of the ...

Potential Flow and Slightly Viscous Flow
1979The goal of this chapter is to present a deeper study of the relationship between viscous and nonviscous flows. We begin with a more detailed study of inviscid irrotational flows, that is, potential flows. Then we go on to study boundary layers, where the main difference between slightly viscous and inviscid flows originates.

Potential flow, viscous flow and compressible flow
1992Abstract At the close of Chapter 16 the Navier-Stokes, continuity, and thermal energy equations for fluid flow were introduced. The present chapter presents finite element formulations for a wide range of fluid flow problems governed by these equations.

Journal of Wind Engineering and Industrial Aerodynamics, 1993
Abstract Potential flow in 2D circular-arc elbows, accelerating elbows and constant-area elbows (similar to radial turbomachine flow channels) is solved by numerical methods. For circular-arc elbows, a formula is obtained which predicts velocities at mid-turn. For other locations, it is shown that velocity distributions can be collapsed into a single

Calculation of potential flows
Doklady Physics, 2005Methods for calculating potential flows based on the theory of functions of a complex variable have been widely used as fundamental investigation methods in many fields of engineering, including seepage theory, elasticity theory, continuum mechanics, heat dynamics, aero- and hydromechanics, electromagnetism, electroand radio engineering, etc. [1‐3].

Potential and Flow Visualization
2007Potential and streamfunction are mathematical functions that cannot be observed directly in the real world, but which turn out to be extremely powerful concerning the calculation and visualization of 2D flow fields. There are applications for all types of fluids, for free flow of gases and liquids, as well as for porous media flow.
