AB Interior ballistics code for unsteady pressure fluctuations in a Davis gun with two moving boundaries was developed using two-phase fluid dynamic model. Numerical simulation results were compared with experimental values to evaluate the feasibility of the interior ballistic code. By comparing numerical analysis with the experimental data, the numerical pressure-time history and muzzle velocities of the projectile and the countermass closely agreed with the experimental data. The strong pressure waves were not observed unlike other works. It was considered that this was owing to the high initial porosity and charge ignition near the center of the gun. The pressure wave amplitude was increased exponentially by the lower initial porosity.
