Numerical simulation of three dimensional transonic flows
14th Atmospheric Flight Mechanics Conference, 1987AbstractThe three‐dimensional flow over a projectile has been computed using an implicit, approximately factored, partially flux‐split algorithm. A simple composite grid scheme has been developed in which a single grid is partitioned into a series of smaller grids for applications which require an external large memory device such as the SSD of the ...

Elementary Three-Dimensional Flows
2017This chapter derives the expressions of the analytical velocity field and gradient (with or without regularization/mollification) for the following elementary three-dimensional flows: point source, vortex point (vortex blobs/vortex particles), vortex segments of constant and linearly varying strengths and dipoles.

Three-Dimensional Irrotational Flow
1967The general case of three-dimensional irrotational flow involves the determination of the velocity potential function which satisfies the boundary conditions and the Laplace equation $${\nabla ^2} = \frac{{{\partial ^2}\phi }}{{\partial {x^2}}} + \frac{{{\partial ^2}\phi }}{{\partial {y^2}}} + \frac{{{\partial ^2}\phi }}{{\partial {z^2}}} = 0$$ (

Three-dimensional flow in cavities
Journal of Fluid Mechanics, 1963The flow inside rectangular and other cavities in a wall has been investigated at low subsonic velocities using oil flow and surface static-pressure distributions. Evidence has been found of regular three-dimensional flows in cavities with large span-to-chord ratios which would normally be considered to have two-dimensional flow near their centre-lines.

Quantitative Flow Visualization of Three-Dimensional Flows
1992Quantitative flow visualization has the advantage of providing instantaneous full field velocity measurement of complex flows. In this article, methods of quantitative velocity measurement are briefly reviewed. Then two benchmark experiments of three-dimensional flow conducted by the authors are presented. The purpose of the experiments is to study the

Steady three-dimensional vortex flow
Journal of Fluid Mechanics, 1966A theory is developed for an incompressible fluid in a steady three-dimensional rotational flow. Solutions are obtained subject to the restriction of small perturbations and are determinant provided that the vorticity distribution along the axis of rotation is known. Effects of viscosity are included.

THREE-DIMENSIONAL SUPERSONIC FLOW COMPUTATIONS
AIAA Journal, 1963ducting fluid implies the solutions of a coupled electromagnetic field-velocity field problem. Moreover, for very dense plasmas, it is implied that viscosity effects must be included because of their effect on the velocity field near the boundaries of the flow.
