Tangential injection to a supersonic flow on a blunted nose
2017
The flow pattern and the heat §ux to a body surface at a tangential gas injecting have been investigated. The cooling air was injected to a §ow through the tangential axisymmetric slot on the spherically blunted cylinder. The experiments were conducted at M ∞ = 6, R e∞, R w = 0.76 · 10 6 , angle of attack α = 0 ◦ -30 ◦ , and the slot width h k / R w = 0-0.021. The mass rate of the injecting gas was G ∗ = g j /(πρ ∞ u 2 ∞ w ) = 0- 0.16. It has been shown that maximum of the heat §ux toward the sphere surface can be sufficiently decreased. Numerical investigations have been carried out using the solution of the NavierStokes equations for axisymmetric two-dimensional (2D) viscous compressible unsteady §ows at α = 0.
