This paper presents a correlation to obtain the surface species concentration on stagnation point with mass injection for hypersonic flow. The can be used determine recombination heat fluxes and oxidation levels ablatives or actively cooled shields in thermochemical equilibrium It explicitly expresses wall as function of freestream conditions, coolant properties, stagnation-point geometry, reve...

Introduction. This announcement deals with the subject of continuous flows in the Euclidean plane. I t has long been known (cf. [ l]) tha t every closed set in the plane is the invariant set of some continuous flow. In a recent paper [2], this author has shown that the same statement is not true for flows all of whose orbits are closed in the plane. In fact a necessary and sufficient condition ...

The main aim of this study was to determine the kinetic energy and momentum coefficients of a small trapezoidal irrigation canal. A laboratory setup with a cyclic flow of water was used. The flow cross section was divided into ten equal sections with nine verticals in between. Pitot static tube was used to measure static and stagnation pressure heads at 1, 2, 3, 4, 5, or 6 point on the vertical...

A two-point second-order uniform box-scheme has been developed for numerical analysis of the gas flow in the boundary layer under the conditions of intensive blowing on the body surface. An effective regularization algorithm has been created. The numerical analysis indicates the second order of the uniform convergence of this box-scheme. Flowfield parameters in the boundary layer near the stagn...
