Abstract:
Aiming at the characteristics of the long tubular powder, a one-dimensional discrete group gas-solid two-phase flow model was established for the large caliber high speed Davis gun with a tubular modular charge. In this model, the tubular modules were described by the Lagrangian system without being assumed as pseudo-fluid, whereas the gas field is described by Eulerian system. The new model was used to simulate a 480 mm Davis gun. The simulation results were compared with test results, and the model was verified to be feasibility. This study provides a new method to research the interior ballistic performance of Davis guns.
Key words:  Davis gun  interior ballistics  two phase flow  numerical simulation
