Hypersonic Asymmetric Flow Near the Stagnation Point of Blunt Nosed Bodies

General Reynolds Analogy for Blunt-nosed Bodies in Hypersonic Flows

In this paper, the relation between skin friction and heat transfer along windward sides of blunt-nosed bodies in hypersonic flows is investigated. The self-similar boundary layer analysis is accepted to figure out the distribution of the ratio of skin friction to heat transfer coefficients along the wall. It is theoretically obtained that the ratio depends linearly on the local slope angle of ...

Oscillatory Flow Near a Stagnation Point

The classical Hiemenz solution describes incompressible two-dimensional stagnation point flow at a solid wall. We consider an unsteady version of this problem, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency. While this problem has already been tackled in the literature for general...

Augmented Burnett-Equation Solutions over Axisymmetric Blunt Bodies in Hypersonic Flow

We obtained augmented Burnett-equation solutions and conducted some preliminary studies on the extent to which the Burnett equations can be used in estimating the departure from the NavierStokes model for hypersonic flow over axisymmetric blunt bodies. The augmented Burnett equation solutions were restricted to the flow inside the bow shock in the stagnation region because of the uncertainty of...

Experimental Studies on Hypersonic Stagnation Point Chemical Environment

Surface Reaction Near a Stagnation Point

To measure rate constants while performing biomolecular interaction analysis (BIA), scientists often use resonant mirror devices such as the IAsysTM. A full mathematical model of the IAsysTM consists of a convection–diffusion equation in a closed well with a reacting surface at the bottom. The flow in the well is complex, but near the sensor, the qualitative nature of the reaction can be analyz...
