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 ...

Three dimensional flow computations with shock fitting
28th Aerospace Sciences Meeting, 1990The paper provides a shock-fitting technique for solving inviscid transonic three-dimensional flows. The continuous flow field is computed by means of an implicit fast Euler solver, which separately integrates compatibility conditions, written in terms of generalized Riemann variables along appropriate bicharacteristic lines.

Abstract Homogeneous (or zero-dimensional), one-dimensional, two-dimensional, and axially symmetric flows are idealizations and all real gas flows are threedimensional. In DSMC computations of the idealized flows with restricted dimensions, the other dimension or dimensions may be regarded as being so small that the statistical ...

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.

One-Dimensional Three-Fluid Flows
2007We call “one dimensional” the flow in pipes or in a pipe networks. We understand here a flow with cross section averaged flow characteristics with special wall boundary layer treatment, like pressure loss modeling, heat transfer modeling etc. The flow axis is of course arbitrarily oriented in space.

Fluid mechanical or CFD simulation (CFD: computational fluid dynamics) is playing an increasingly important role in the simulation of engine processes, as it makes possible the most detailed physical description of the relevant processes. The most diverse processes in the engine field are considered, like charge changing, in-cylinder flow, exhaust gas ...

Modeling Three-Dimensional Flow
1987The basic laws governing the flow of water were presented in the previous chapter. However, one cannot solve flow problems by using only these laws. Equation (2.1.19) is a single equation in two dependent variables: q(x, y, z, t) and o(x, y, z, t). It can also be regarded as three equations in four unknowns o, q x , q y ,q z .

AS far as the author is aware, no attempt has yet been made, either on the experimental or on the theoretical side, to extend to three dimensions the conceptions regarding the formation of a vortex street in the wake of a body, as developed by Karman and Rubach for two dimensions.

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.
