Download or read book Effect of Surface Roughness on Characteristics of Spherical Shock Waves written by Paul W. Huber and published by . This book was released on 1955 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
