Numerical Simulation of Roughness Effects on Flow Entrance in Flat Micro-channels
摘要
Abstract
The influence of absolute roughness and relative roughness on entrance flow in parallel flat micro-channels was investigated numerically with triangular toothed roughness cell as surface roughness of solid by using CFD technologies.The influences of solid surface roughness and fluid velocities on the flow entrance length of parallel flat micro-channels were researched, the influences of relative roughness on critical Reynolds number were also studied herein.关键词
