Guderley's self-similarity solution r = r(0)(1 - t/t(0)) a for strong converging cylindrical shocks is investigated experimentally for three different gases with adiabatic exponents gamma = 1.13; 1.40; and 1.66 and various values of the initial Mach number. Corresponding values of the similarity exponent a which determines the strength of shock convergence are obtained for each gas thus giving the variation of alpha with gamma. Schlieren imaging with multiple exposure technique is used to track the propagation of a single shock front during convergence. The present experimental results are compared with previous experimental, numerical, and theoretical investigations.
