| 摘 要： | 本文运用非平衡态热力学中最小熵增原理,分析了层流和湍流流动在接近热力学平衡定态时的特性。特别是在湍流流动中,舍弃了以往一些经验性的假设,指出流动处于局部机械平衡时可由最小熵增原理导出速度和温度分布。反之亦揭示了充分发展的湍流遵循最小熵增原理的这一机理。

| Abstract: | The present paper has analysed the characteristics of laminar and turbulent flow getting near constant states of equilibrium with the fundamental principle, minimum entropy generation in non-equilibrium thermodynamics. Especially it has been brought to light, without some of old experimental assumptions, that velocity or temperature distribution follows the principle of minimum entropy generation, when turbulent flow is in local mechanics equilibrim. |
