Three‐dimensional Hiemenz stagnation‐point flows
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2020AbstractA modification of Hiemenz's two‐dimensional outer potential stagnation‐point flow of strain rate a is obtained by adding periodic radial and azimuthal velocities of the form and , respectively, where b is a shear rate. This leads to the discovery of a new family of three‐dimensional viscous stagnation‐point flows depending on the shear‐to ...

Three-Dimensional Flow around Blunt Bodies
Journal of Spacecraft and Rockets, 2003The three-dimensional flowfield around blunted bodies traveling at supersonic speed is computed using a time-dependent technique. A similar technique has been used by one of the present authors to compute two-dimensional and axisymmetric flowfields around blunted bodies and has proved to be highly successful when compared with experimental results. The

Aircraft Engineering and Aerospace Technology, 1929
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.

A three-dimensional cerebrovascular flow phantom
Medical Physics, 1999We have constructed a life-sized fully three-dimensional (3D) rigid flow-through model of the cerebral vasculature. Average vessel diameters and lengths, taken from published values in the literature, were used to describe the geometry of our phantom; numerically controlled machining techniques were used to fabricate the model. Inflow to the phantom is

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 ...

Three-Dimensional Laminar Flow in Ducts
Numerical Heat Transfer, Part B: Fundamentals, 1981A finite-element marching procedure is presented for the calculation of transport processes in three-dimensional parabolic flows As in corresponding finite-difference procedures, equations are solved one after the other. Similarly, longitudinal and cross-stream pressure gradients are uncoupled.

Three-dimensional flows over backward facing s.tif
International Journal of Numerical Methods for Heat & Fluid Flow, 1999Three-dimensional flows over backward facing s.tif are analysed by means of a finite element procedure, which shares many features with the SIMPLER method. In fact, given an initial or guessed velocity field, the pseudovelocities, i.e. the velocities that would prevail in the absence of the pressure field, are found first. Then, by enforcing continuity

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 ...
