Analysis of Factors Affecting Average Velocity of Capillary Rectangular Channel Based on Orthogonal Test Method

In order to analyze the factors affecting the average velocity of capillary rectangular channel,this paper deduces the factors affecting the average velocity through the formula,analyzes the flow velocity in terms of the channel width,channel depth,and channel length by the three-factor three-level orthogonal test table and obtains the average velocity through CFX simulation.Then,the influence of various factors on the average velocity of the capillary rectangular channel is obtained.Among them,the channel width and channel depth have a relatively great effect on the average velocity of the capillary channel.In addition,the optimal level combination is obtained.Therefore,a clear analysis of the factors affecting the average velocity of the capillary rectangular channel is given,which is of reference significance for the optimization analysis of heat transfer in capillary rectangular channels.
