摘　　要：为研究TA15钛合金在火药燃气流作用下的烧蚀特性,基于计算流体动力学方法、离散相模型和动网格技术建立其动态烧蚀模型,实现了TA15钛合金试片结构型面衰退和内流场变化的双向耦合分析。利用动态烧蚀模型对TA15钛合金试片的二维非定常流烧蚀过程开展了仿真计算,以模拟火药燃气流对试片的冲刷过程,探究其烧蚀特性。不失一般性,利用半密闭爆发器搭建试验验证平台,对典型工况的仿真结果进行试验验证。结果表明:烧蚀量计算值达到试验值的92.3%,说明动态烧蚀模型可以准确预测TA15钛合金试片壁面烧蚀情况。该研究为TA15钛合金炮口制退器的研制奠定了重要基础。To study the ablation characteristics of TA15 titanium alloy under the action of gunpowder gas,the dynamic ablation model is established based on the calculated fluid dynamics method,discrete phase model and dynamic grid technology,and the bidirectional coupling analysis of structural coupling analysis of structural surface decline and internal flow field change of TA15titanium alloy test piece is realized.The dynamic ablation model is used to simulate the two-dimensional non-steady current ablation process of TA15 titanium alloy test piece,so as to simulate the scour process of gunpowder gas flow on the test piece and explore its ablation characteristics.Without generality,the semi-closed outbreak period is used to build a test and verification platform to test and verify the simulation results of typical working conditions.The results show that the calculated ablation value is 92.3%,which shows that the dynamic ablation model could accurately predict the wall ablation situation of TA15 titanium alloy test sheet.This study laid an important foundation for the development of TA15 titanium alloy muzzle brake.
