火药传热特性与Tait方程的应用

Characteristics of Propellant Heat Transfer and The Applieations of Tait Equation.

该文通过求解单颗粒火药非稳态温度场,给出了临界温度边界层曲线,讨论了Tait方程的应用条件。结果表明,在多孔火药床的燃烧转爆轰过程中,火药内部温度边界层厚度小于火药粒径的百分之一,火药状态可用Tait方程描述。

The critical curve of temperature boundary layer was prasentedand application conditions of Tait equation were discussed, on the basis of thesolution of unsteady temperature field in single spherical propellant in this pa-per. The results showed the thickness of temperature boundary layer in thepropellant is less than one percent of the diameter of the propellant and Tait e-quation can be used to describe the state of the propellant during the deflagra-tion to detonation transition in porous propellant bed.
