节流毛细管设计的类比法

The Analogical Method for the Design of Adiabatic Capillary Tubes

从毛细管的微分方程模型出发,建立了绝热毛细管类比设计法的理论公式,提高了毛细管的设计效率.

The capillary tube expansion device is widely used in the refrigerating and air-condition-ing equipment. The analogical method is one of the most popular design methods for capillary tubes. However, it is an empirical method. Based on the differential governing equations of an adi-abatic capillary tube, the theoretical formulation of the analogical design method has been devel-oped here. It is simple but helpful to engineers in improving designing efficiency.
