支撑片排布对换热器性能影响的数值研究
Numerical Research on Performance of Heat Exchanger under Different Arrangement of Support Pieces
摘要
Abstract
The models of general support pieces arrangement and the new pieces arrangement of 1/8,1/4,3/8,1/2 were established,respectively.CFD analysis software FLUENT was used to carry out the numerical simulation.And performance of heat exchanger with different support pieces arrangement was investigated.Results show:through reasonable arrangement of support pieces,the disturbance of local and overall fluid flow in shell side can be effectively improved,the synergy between velocity field and temperature field of shell side is optimized,and the heat transfer of heat exchanger can be enhancement.Under different fluid flow,the comprehensive performance is the highest when support pieces arrangement is 1/8,and the heat transfer performance is the highest when support pieces arrangement is 3/8,compared with general support pieces arrangement,the comprehensive performance and heat transfer performance increased 4.42% to 6.29% and 8.76% to 10.51% respectively.关键词
