Abstract

A detailed literature review on the flow characterization of the capillary tubes is presented in this paper. The flow behavior is reviewed for straight, helically, and spirally coiled capillary tubes at different operating and geometric conditions by considering various aspects in the tube. This paper summarizes experimental and numerical study on the adiabatic and nonadiabatic straight and coiled capillary tubes at different geometries conditions. The vital information of the range of the tube geometry and operating conditions are discussed, which can be utilized for further studies on the capillary tube. Various methodologies with generalized correlations are indicated. It has been observed that there are even more studies need to do with environmentally friendly refrigerants with various practical aspects in the capillary tube. It would be interesting to find the coiling effect on the design and simulation of the capillary tube. In addition to that more experimental and numerical studies need to explore the nonadiabatic coiled capillary tube. It would be fascinating to study the metastable condition in the capillary tube and set suitable relations to present its effect on the mass flow rate.
直管和盘管毛细管流动特性研究进展
本文对毛细管的流动特性进行了详细的文献综述。通过对管内各方面的考虑,综述了直管、螺旋管和螺旋管在不同操作和几何条件下的流动特性。本文综述了不同几何条件下绝热和非绝热直管和盘管的实验和数值研究。讨论了毛细管几何形状范围和工作条件的重要信息,为毛细管的进一步研究提供了依据。指出了具有广义相关性的各种方法。据观察,对于毛细管中各种实用方面的环保制冷剂,还需要进行更多的研究。在毛细管的设计和仿真中,研究线圈效应是一个很有意义的问题。此外,还需要对非绝热的螺旋毛细管进行更多的实验和数值研究。研究毛细管内的亚稳态状态并建立合适的关系式来描述其对质量流量的影响将是一个有趣的问题。
