Pulsation Calculation of Cylindrical Underwater Gas Explosion Products in Well

Abstract

The paper considers a mathematical model of pulsation process of cylindrical underwater gas explosion products in the well at gas-impulse regeneration filters. A differential equation of the second-order with constant coefficients has been derived. A special calculation program has been developed to solve the equation. Expressions for calculation of maximum radius of cylindrical explosion chamber at the end of expansion process and pressure impulse in the first half-period pulsation.
