Abstract
Abstract Aiming at the problem that the barrel life of a large calibre artillery is obviously lower than the international advanced level, and the thermal erosion inside the barrel is serious, based on modern interior ballistic theory and heat transfer theory, a simulation of one-dimensional two-phase flow interior ballistic, heat exchange process between gas-solid two-phase flow and the barrel is carried out. The influence of maximum pressure in bore, charge, propellant explosion temperature, barrel structure and other parameters on the barrel temperature is obtained, and the correlation between the barrel temperature and parameters of interior ballistic and charge is analyzed, providing direction for the design of low-ablation interior ballistic and charge.
