摘要
目前两相流不稳定性理论分析的主要工具是频域法和时域法。为更便于使用,有必要找出该领域判定稳定性的能量原理(李雅甫诺夫型判据)。本文采用李雅甫诺夫稳定性理论和非平衡态热力学理论,将广义熵的二阶变分δ~2Z作为能量函数引入两相流不稳定性分析领域,并推得一维固定边界条件下的显式能量原理。
There are two ways which are called the frequency domain and time domain method have been developed to analyse two phase flow instability and it is suitable to find the third method-energy principle in this field.with the help of lyapounov's stability theory and nonequilibrium thermodynamic theory, the present paper introduces the second order variation of general entropy as energy function into two phase flow instability field, and induces an explicit energy principle under the condition of one dimensional solid boundary.
