Stagnation Point Probes in Hypersonic Flow
2017Disturbance level measurements are carried out in the Hypersonic Ludwieg Tube Braunschweig (HLB) at \(\text{ Ma } = 5.9\) considering three shapes of stagnation point probes (SPP) and two different types of high speed surface sensors. Navier Stokes mean-flow solutions are produced for the flow around the front shapes to increase the understanding of ...

Homotopy Solution for Stagnation-Point Flow
Communications in Theoretical Physics, 2012This article reports the homotopy solution for stagnation point flow of a non-Newtonian fluid. An incompressible second grade fluid impinges on the wall either orthogonally or obliquely. The resulting nonlinear problems have been solved by a homotopy analysis method (HAM). Convergence of the series solutions is checked. Such solutions are compared with

Stagnation-Point Flow of Rarefied GaS
Journal of the Physical Society of Japan, 1967This paper deals theoretically with the stagnation-point flow of a rarefied gas. Representative Mach number M S taken in the continuum flow region is assumed to be small and thus the analysis is based on the linearized B-G-K equation. A method of solution is developed in which the continuum flow and the Knudsen layer flow are considered successively ...

Stability of stagnation points in rotating flows
Physics of Fluids, 1997The Lifschitz and Hameiri theory for short-wave instabilities is used to show that any steady inviscid plane flow subjected (or not) to a Coriolis with perpendicular angular velocity vector is unstable to three-dimensional perturbations if Φ(x0)<0 on a stagnation point located at x0.

Axisymmetric stagnation point flow in magnetohydrodynamics
Applied Scientific Research, Section B, 1961This paper contains a theoretical treatment of the axisymmetric stagnation point problem in magnetohydrodynamics. Two distinct arrangements of the magnetic field are considered, with the lines of force lying in the plane of, and perpendicular to the streamlines, respectively.

Impinging rotational stagnation-point flows
International Journal of Non-Linear Mechanics, 2017Abstract A rotational stagnation-point flow of fluid density ρ1 and kinematic viscosity ν1 impinges normal to another rotational stagnation-point flow of fluid density ρ2 and viscosity ν2. Results are compared with a previous study on the normal impingement of two Homann stagnation-point flows for which the flow in the far field is irrotational.

Inviscid non-equilibrium flow in the vicinity of a stagnation point
1993Summary: A model is proposed for the inviscid two-dimensional blunt-body flow in chemical nonequilibrium in the vicinity of the stagnation point. It is based on the use of the incompressible flow approximation for the density and velocity fields, and on a local linearization of the species convection equations about equilibrium values.
