摘要
针对舰载导弹同心筒发射装置,建立了燃气流与发射筒间的换热模型。建模中考虑了发射筒结构的复杂性,燃气流的高温、高速等特点,以及筒内燃气流场流动与换热的强耦合性。通过对筒内燃气流场的全流场非稳态的数值模拟,得到了同心筒内外筒壁面温度的分布规律。
A heat exchange model between the combustion-gas flow and the launching tube was constructed for shipborne missile concentric canister launcher (CCL). The structural complexity of the CCL, the high-temperature and high-velocity features of the combustion-gas, and the strong coupling of the combustion-gas flow and heat exchange have all been considered during modeling. With the unsteady numerical simulation of the integral combustion-gas flow being carried out. the temperature distribution patterns on the internal and external tube walls were obtained.
