摘要
利用X光高速动态成像技术拍摄分析了六氟化硫在熔融锂中浸没喷射反应的过程,并采用有限差分方法计算了锂与六氟化硫反应的温度场、反应物及其产物的质量分数分布、反应混合物的密度分布及浸没喷射的射流长度和宽度.给出了预测六氟化硫在锂中浸没喷射的射流长度的半经验关系式.
Li/SF_6 reaction is being used as Rankine cycle heat sources for undersea vehicle propulsion systems.X-ray high-speed radiography technique has been used to investigate the submerged penetration of sulfur hexafluoride into molten lithium for a better understanding of Li/SF_6 reaction.Detailed profiles of density,temperature,jet dimensions and mass fraction of the reaction have been computed.A semiempirical jet length equation is also presented.The results and the predictions of the jet length equation are in agreement with the experimental data.
