A CONTRIBUTION TO THE SOLUTION OF MIXED PROBLEMS OF TRANSONIC AERODYNAMICS

Publisher Summary This chapter presents the solutions for the problems of transonic aerodynamics. In the new branches of technique, such as for atomic physics and automatic control, electronic computers are widely used. The methods of aerodynamical investigations had been established long before electronic computers appeared. Till recently, aerodynamics was a part of mechanics whose basic laws were established by Euler and Navier–Stokes. Modern aerodynamics encroaches upon the domains of chemical kinetics, kinetic theory of gases, and electrodynamics. In the Computing Center of the Academy of Sciences of the U.S.S.R. and some other institutes, the problem was set to develop the methods of solving the equations of classical aerodynamics using electronic computers. The most difficult problems are mixed problems, where in some parts of flow velocities are subsonic and in others, supersonic.
