一、问题的引出 不可逆过程热力学是一门在近几十年中迅速发展起来的新兴学科.它以非平衡态为主要研究对象,取得了许多重要成果,也引起学术界越来越多的重视.但这门学科还比较年轻,有些还显得不够成熟.如对粘性流体运动由于流动现象较复杂,运动方程的非线性,使不可逆过程热力学仅在忽略流动惯性项时得到描述粘滞现象 First, the problem leads to irreversible process Thermodynamics is a rapidly emerging emerging disciplines in recent decades.It non-equilibrium as the main research object, has made many important achievements, but also attracted more and more attention in academia However, this discipline is still relatively young, and some of them are still not mature enough.For example, due to the complexity of the flow phenomenon of viscous fluid and the nonlinearity of the equation of motion, the thermodynamics of irreversible process can be described only when the inertia term is neglected
