An investigation has been conducted on a small-scale test layout in which direct observation of the shock-wave movement with time could be made in order to determine the effects of surface roughness on the characteristics of spherical shock waves. Data were obtained with 15-gram pentolite charges at four heights of burst, both for a smooth surface and for a surface completely covered with pyramid-shaped roughness elements. The observations calculated in determinations of shock peak over-pressure and Mach stem height as a function of distance for each test condition.

Download The Effect of Surface Roughness on the Diffraction of a Shock Wave Around Two-dimensional Blocks Book in PDF, ePub and Kindle
The purpose of these experiments conducted in the shock tube was to obtain qualitative information concerning the effect of various types and degrees of surface roughness on the diffraction of a shock wave about a two-dimensional model. A series of shadowgraphs was taken of the various blocks in the shock tube with incident over-pressure of 6 and 9 psi. Qualitative analysis of the data indicates that surface roughness reduces the velocity of the shock across the top near the rough surface and tends to hinder the developmemt of the front top vortex appreciably, but does not affect the development of the rear vortex to as great an extent.
