摘要
该文采用了管内边界层流动的二维模型,研究了火炮身管内边界层流动和传热的数值计算。并且把身管内气流对壁面传热和管内热传导的解结合起来求解,以提供膛内传热分析中重要的壁温值和对流传热值,数值计算结果与文献报导较一致。
The thesis uses a two-dimensional model to conduct the numer-ical computation of boundary layer flow inside the gun barrel. Convective heattransfer from the gas flow to the gun wall and conduction solution inside thetube are coupled to provide the important wall temperature and convectionheat flux the heat transfer analysis inside the gun tube. The numerical resultsare in agreement with those from references.
