INTERACTION OF TWO NONIDENTICAL CONVERGING SKEW SHOCK WAVES IN A GAS WITH A CONSTANT POLYTROPIC INDEX S. K. Andilevko UDC 534.2 Consideration is given to the interaction of two skew shock waves (SSW) moving at different velocities in opposite directions to each other in a gas with a constant polytropic indexk. An analysis is made of the changes in configurations of the shock waves due to their interaction at round angles of contact within the range 0 -pi. JEPTER74920199917 JEPTER7492017
