Numerical and Experimental Simulation of Medium Compression Effect at Flowing Around A Wing Profile
Abstract
Simplified theoretical models are quite often used in aerodynamical investigations to solve the problems of flowing around the aircraft elements with a compressed flow in particular the model of incompressible liquid based on using of the known correction factor which is a function of the Mach number. The similar approaches have a whole series of restrictions with conditional and interdependent limits. By this, a trusty information made in the frames of models verification, such as a pressure distribution on the surface, or nicer characteristics, for example, flow downwards, even by flowing around bodies of a non-complicated form is not exhaustive by no means. This work is to make up a deficiency, in which on the example of flowing in the vicinity of a symmetrical wing profile with a relative thickness of 12% the numerical and experimental data have been obtained. These data allow to evaluate an adequacy level of different modeling ways of the compressed medium effects.
