Spatial subsonic flows in areas with composite geometry

The flows of combustion products with three-dimensional pattern will be realized in channels of solidpropellant propulsive plants. Because of large complexity of the solution three-dimensional gasdynamics problems of analytical investigations of flows in the field of the composite form are small. The experimental measurement of gas-dynamics parameters of hyper-thermal flows is even more complicated problem. Therefore experimental simulation of flows in power plants are, as a rule, on cold air with observance of a similarity on Mach numbers and Reynolds. The obtained outcomes can be utilized for testing of techniques of calculation of three-dimensional flows.
