Abstract: (539 Views)

Porous explosives such as octogen (HMX) are classified as high-sensitivity secondary explosives, which are in powder form and are usually charged by the pressing method. Investigating the behavior of these materials under shock waves has always been a challenge for researchers. In this research, the hydrodynamic behavior of these materials in the shock tube was investigated in a two-phase manner. In the modeling of two-phase systems with the presence of shock waves, the differential equations are hyperbolic; Therefore, to capture the pressure pulse in the shock tube, a Riemann solver is needed. In this research, Ecogen software was used for simulation. This software is equipped with Kapila's multiphase model and uses a Riemann solver with the ability to capture shock waves to solve differential equations. Simulation of the shock tube in two modes of pressure pulse with low amplitude and pressure pulse with high amplitude was carried out using two-phase Kapila model and data from previous researches were used for validation. Comparing the results of the simulation with the data of previous researchers showed a difference of less than 5%.

Keywords: Gas-solid mixture, shock tube, octogen (HMX), cold flow, Kapila two-phase model
