Conjugate Heat Transfer
耦合传热
This lesson covers the flow of Refrigerant R-123 (Real Gas) through a heated liquid cold plate located in an open air filled environment.
The objective is to introduce the set up of a conjugate heat transfer analysis using multiple fluid domains.

抱负气体为假想的气体；其特性为：
气体分子间无作用力
气体分子本身不占有体积
气体分子与容器器壁间发生弹性碰撞
真实气体在愈低压，愈高温的状态，性质愈接近抱负气体；最接近抱负气体的气体为氦气；
真实气体
抱负气体及真实气体
