Simulation study of flushing ablation by gas-solid two phase flow of artillery barrel

Abstract For the wear problem of artillery barrel bore during launching, this work uses particle erosion and deposition modules in Fluent Software to simulate process gunpowder gas particles on barrel, analyses steady transient states simulation results, compares effects different influencing factors wear. The results showed that a certain range, rate wall was positively correlated with velocity mass flow. 0.25 mm critical size, decreased increase diameter. This information is valuable for prolonging service life barrel.
