A method for calculating the pressure change in cylindrical cavities for studying the outflow of detonation products during the explosion of elongated explosive charges in boreholes and boreholes

The paper proposes a numerical method for solving the problem of the theory of a strong point explosion and for calculating the excess pressure that occurs in a cylindrical cavity during an explosion. At the same time, the proposed sequence of numerical simulations provides a relative error of no more than 15% compared to the analytical and experimental data and will allow us to apply this model to study the PD expiration during the explosion of an elongated explosive charge.
