流体非平衡相变强化传热的场协同分析

ANALYSIS OF FIELDS SYNERGISM IN NON-LINEAR ENHANCED TRANSFER PROCESSES OF FLUID PHASE CHANGE OF NON-EQUILIBRIUM

提出了有序度概念并在此基础上 ,论述了非平衡相变是有序度的突变 ,其传递强度可以得到突变的增加 .如果能够在非平衡非线性过程中协调场的参数 ,那么 ,就有可能以小的能耗而获得传递过程的最大强化 .以自然对流和湍流为例论述了上述观点 .

On the basis of the definition of the order agree,it is discussed that the order agree of the critical phase changes of non-equilibrium has a sudden change and the transfer intensity may get a sudden increase.If the parameters of fields are coordinated in the non-equilibrium and non-linear progress,it is possible that the maximal augmentation of transfer is achieved by a little energy dissipation.The paper discusses the above ideas with the nature convection and turbulent flow.
