Abstract
Using a high speed JOHNNLLC computer and a program which allows the solution of the partial differertial equations governing hydrodynamic motion in spherical geometry, the problem of the blast wave from a point source in air was carried out. The methods are described and the equation of state for air is given. The results of the particular solution for a point source is covered, giving shock values of pressure, density, particle velocity, temperature and dynamic pressure as functions of the shock radius and of the peak overpressure. The time histories of the same variables are given for a number of distances from the source, as well as values of the durations of positive phases and impulses from overpressure and from dynamic pressure.
