BLAST WAVE THEORY
Abstract
A method to find approximate solution of an idealized model of the blast wave problem is developed, the gasdynamic motion is initiated by an instantaneous energy release from a point source (or line, or plane source). transformation of variables is introduced with a similarity parameter x as an independent variable along with a quantity less sensitive to the phenomenon. This reduces the fundamental system of equations of the problem to a manageable form for the approximation, which is conveniently performed in a power series expansion in the variable y and the coefficients of the expansion can be determined successfully from the systems of ordinary differential equations. The method has been applied to many problems of the similar type, with some modifications necessary for each case, to blast wave, the propagation of the blast wave in the non-uniform medium, exploding wire phenomenon, magnetohydrodynamics cavitation and thunder.
