Abstract

A modification of the well-known wide-range equations of state of Nigmatulin–Bolotnova is proposed for describing the high-speed adiabatic-compression of vapor of tetradecane in the metastable region in physically consistent way. The modification is based on taking into account the effect of delay of vapor condensation processes under high compression rate. It is useful for studying various phenomena associated with high-speed compression of vapor of tetradecane when the compression is close to adiabatic. It can, in particular, be applied to investigating high-speed collapse of cavitation bubbles in tetradecane. The technique of the proposed modification can also be used for a similar correction of other equations of state built on the basis of the generalized Born–Mayer potential.

高速蒸汽压缩亚稳态区域状态方程的修正

摘要

提出了对著名的Nigmatulin–Bolotnova状态方程的修改，以物理上一致的方式描述亚稳区域中十四烷蒸气的高速绝热压缩。该修改基于考虑到在高压缩率下蒸气冷凝过程的延迟的影响。当压缩接近绝热时，对于研究与十四碳蒸气的高速压缩有关的各种现象非常有用。它尤其可以用于研究十四烷中空化气泡的高速破裂。提出的修改技术也可以用于基于广义Born-Mayer势建立的其他状态方程的类似校正。
