基于Fluent流体传热仿真的毛细管风道设计优化
Optimization of air duct design of a capillary column based on Fluent fluid heat transfer simulation
摘要
Abstract
This study aims to address the problem of uneven axial heat dissipation in separated sections of capillary column cooling ducts.A variable-section air supply duct was designed.The Fluent simulation software was utilized to model and numerically simulate the duct design,enabling the optimization of various parameters including duct impact angle,inlet and outlet shape,and duct length dimensions.The reliability of the design was validated through measurements of the air velocity at the duct outlet and the temperature at the column surface inside the duct.The results indicate that the optimized capillary cooling duct achieves a more uniform air velocity at the outlet,resulting in a reduced axial temperature difference and a significant improvement in temperature control.The experimental test results closely align with that of simulations,which confirms that the average air velocity at four outlets ranges from 10.38 to 10.67 m·s-1,and the temperature difference along the column surface is reduced within±1℃.The optimized design of the capillary cooling duct has great guiding significance in enhancing cooling efficiency and addressing poor uniformity in separation section.关键词
