Transonic Shocks in Multidimensional Divergent Nozzles

We establish existence, uniqueness and stability of transonic shocks for steady compressible non-isentropic potential flow system in a multidimensional divergent nozzle with an arbitrary smooth cross-section, for a prescribed exit pressure. The proof is based on solving a free boundary problem for a system of partial differential equations consisting of an elliptic equation and a transport equa...

Anisotropic Mesh Adaptation for Transonic and Supersonic Flow Simulation

We present an efficient tool for the numerical simulation of high speed flows in two and threedimensional domains. The space discretization is carried out with the finite volume method on unstructured triangular and tetrahedral meshes. In order to achieve sufficiently accurate capturing of shock waves, we have applied the anisotropic mesh adaptation technique which seems to be very suitable for...

XIX Biannual Symposium on Measuring Techniques in Turbomachinery Transonic and Supersonic Flow in Cascades and Turbomachines PROBES IN TRANSONIC FLOW

A constraint exists for intrusive probes in transonic flow which leads to a complete insensitivity to static pressure at Mach number Ma=1. Nearby Mach number unity different types of probes are affected more or less by the reduced sensitivity to static pressure or Mach number. In this paper three types of probes are compared and it is shown that the reduced sensitivity near Ma=1 causes large er...

The Transonic Flow in the Throat Region of a Two-Dimensional Nozzle with Walls of Arbitrary Smooth Profile

A solution is presented for the flow in the throat region of a two-dimensional nozzle with an arbitrary smooth profile. The velocity components are determined as series expansions in ascending powers of R-~ where R is the mean radius of curvature of the profile at the throat measured in throat half-heights. The first three terms of the series solution are given, and some properties of the flow ...

Adaptation of Structured Grid for Supersonic and Transonic Flows

Two distinct redistribution grids - adaptation techniques, spring analogy and elliptic grid generator are applied to two-dimensional steady, inviscid, shocked flows, and the ability of each technique is examined and compared. Euler equations are solved base on Roe's Reimann solver approach to simulate supersonic flow around a sphere, transonic flow about an airfoil and supersonic flow in a symm...
