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.

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 .

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 ...

The three dimensionality of the intraglottal flow
The Journal of the Acoustical Society of AmericaVoice production depends critically on fluid–structure interactions within the glottis, especially during the closing phase of phonation where flow separation and pressure transients shape vocal output. We present a novel application of time-resolved tomographic particle image velocimetry (tomo-PIV) to visualize 3-D intraglottal airflow in opaque ...

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 Fields of Flow
1934The functions ϕ and ψ as hitherto employed and arising out of the development of some function of (x + iy) are not applicable to fields of flow in three-dimensional space. The definition of ψ, however, remains, as in Division A VII 1—a function whose derivative along any direction in space will give the velocity in that direction.

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 $${\nabla ^2} = \frac{{{\partial ^2}\phi }}{{\partial {x^2}}} + \frac{{{\partial ^2}\phi }}{{\partial {y^2}}} + \frac{{{\partial ^2}\phi }}{{\partial {z^2}}} = 0$$ (
