Abstract : The results of an experimental study of the attenuation of a shock wave traveling through a non-uniform region were compared to the results of a numerical solution developed from the continuity, momentum, energy, and Rankine-Hugoniot equations using G. B. Whitham's rule. The region of non-uniformity consisted of a converging section which was porous. The angles of convergence tested were 0, 4, and 6-degrees having a maximum porosity of approximately 44%. The 0- and 4-degree channel had a height of 3/4 in. and the 6-degree channel had an equivalent height of 1-1/2 in. with the porous section of both convergent channels being 4 in. long and the 0-degree channel 3-1/2 in. long.
