Approximate Spherical Blast Theory and Laser-Initiated Pellet Microexplosions

摘要

Equations are presented which describe the shock speed and overpressure as a function of radius for strong spherical blasts in cases where the source mass is not negligible. Approximations similar to those used in the Taylor-Sedov approximate theory are employed. Sample calculations are presented for a laser-initiated 1-MJ (debris energy) pellet microexplosion, and compared to Taylor-Sedov approximate theory solutions.
