Experimental Studies on Hypersonic Stagnation Point Chemical Environment

A Quasi-onedimensional Approach for Hypersonic Stagnation-point Ows Lehr-und Forschungsgebiet F Ur Mechanik

An approximate method for the eecient calculation of stagnation streamline quantities in hypersonic ows about spheres or cylinders is suggested. Based on the local similarity of the ow eld the two-dimensional Navier-Stokes equations are simpliied to a one-dimensional approximation for the stagnation streamline. The dimensionally reduced equations are solved with an implicit nite-volume scheme. ...

Unsteady Heat and Mass Transfer Near the Stagnation-point on a Vertical Permeable Surface: a Comprehensive Report of Dual Solutions

In this paper, the problem of unsteady mixed convection boundary layer flow of a viscous incompressible fluid near the stagnation-point on a vertical permeable plate with both cases of prescribed wall temperature and prescribed wall heat flux is investigated numerically. Here, both assisting and opposing buoyancy forces are considered and studied. The non-linear coupled partial differential equ...

Heat Transfer on a Hypersonic Sphere with Gas Injection

The interaction of a diffusing outgas flow from a sphere nose opposing a hypersonic free stream is studied numerically using the direct simulation Monte-Carlo technique under the transitional rarefied-gas-flow regime conditions at Knudsen numbers from 0.016 to 1.5 and blowing factors from 0.15 to 1.5. Strong influences of the blowing factor (the ratio of outgas mass flux to upstream mass flux) ...

Unsteady Stagnation Point Flow and Heat Transfer over a Stretching/Shrinking Sheet with Suction or Injection

The unsteady stagnation point flow and heat transfer over a stretching/shrinking sheet with suction/injection is studied. The governing partial differential equations are converted into nonlinear ordinary differential equations using a similarity transformation and solved numerically. Both stretching and shrinking cases are considered. Results for the skin friction coefficient, local Nusselt nu...
