Intracardiac Flow Analysis: Techniques and Potential Clinical Applications
Journal of the American Society of Echocardiography, 2019&NA; Analysis of intracardiac flows has gained increasing interest in the last years. This analysis has become possible due to the development of technologies for noninvasive cardiovascular imaging, which allow visualization and quantitation of ...

The Physics of Fluids, 1964
An investigation is made of some questions pertaining to the stability of potential flow. A formalism due to Eckart is adapted to obtain equations for the perturbations of a known steady potential flow, in a coordinate system defined by the potential function and the stream function.

This chapter presents the time-dependent three-dimensional equation governing the evolution and the steady state compressible potential associated with the irrotational flow of compressible fluids. Some particular cases of the complete equations are presented, followed by a classification of Partial Differential Equations.

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.

Journal of Fluid Mechanics, 2003
Potential flows ${\bm u} = {\bm\nabla} \phi$ are solutions of the Navier–Stokes equations for viscous incompressible fluids for which the vorticity is identically zero. The viscous term $\mu \nabla^2 {\bm u} = \mu{\bm \nabla}\nabla^2\phi$ vanishes, but the viscous contribution to the stress in an incompressible fluid (Stokes 1850) does not vanish in ...

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, 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. Of particular interest are the uvp or primitive variable formulations for Stokes flow.

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.
