摘要
Abstract
A numerical analysis of flow patterns in serpentine micro-channels was studied using a CLSVOF (coupled level set and volume of fluid method) multiphase model. The effect of contact angle, surface tension, liquid viscosity and cross section shape on flow pattern was systematically investigated after verifying the rationality of the model. The air-water two-phase flow pattern map was drafted under different flow conditions. Moreover, in order to analyze the effect of section shape and aspect ratio on flow pattern, the flow map between simulation results and different sections with same equivalent diameter micro-channels was compared. These results provide a basic idea for micro-channel design.关键词
