速度场和温度场中的熵产生在动量和热传递问题中是非常重要的。在确定了这个后处理量之后，就可以获得关于问题物理学的许多细节。第二定律分析（SLA）是一种概念性的工具，用于确定速度场和温度场的损失，并有助于评估复杂的对流传热过程。结合熵产生这三个方面进行了详细讨论，并说明了几个例子。[DOI 10.1115/1.4005128]
Entropy generation in a velocity and temperature field is shown to be very significant in momentum and heat transfer problems. After the determination of this postprocessing quantity, many details about the physics of a problem are available. This second law analysis (SLA) is a tool for conceptual considerations, for the determination of losses, both in the velocity and the temperature field, and it helps to assess complex convective heat transfer processes. These three aspects in conjunction with entropy generation are discussed in detail and illustrated by several examples. [DOI: 10.1115/1.4005128]
