THE PRESHOCK SOUND VELOCITY FIELD OVER INORGANIC AND ORGANIC SURFACES. A PROBLEM ANALYSIS AND STATUS REPORT

Abstract

Existing information concerning the development, during nuclear detonations, of preshock sound velocity fields caused by irradiation of inorganic and organic surfaces is anayzed. Experimental results are compared with available theoretical analyses and the influence of surface thermal properties is discussed. Surface temperatures calculated from theoretical results based on the assumption of a homogeneous media and using published thermal properties are inconsistent with temperatures measured during actual detonations. A vigorous experimental program appears necessary in view of the deficiencies of theoretical attack, especially in the case of organic surface materials. pecific recommendations on the objectives of such programs are presented. Conventional modes of convective heat transfer are shown to explain observed depths of thermal layers over inorganic surfaces if compressibility is considered. (Author)
