折流板对锥螺旋管束振动及强化传热的影响
Effect of baffle plate on vibration and enhanced heat transfer of conical spiral tube bundles
摘要
Abstract
To further enhance the comprehensive heat transfer capacity of conical spiral elastic tube bundle(CSETB)heat exchangers,the vibration and heat transfer characteristics of each CSETB in the heat exchanger were numerically investigated based on five different conical baffle(CB)angles(α).It is shown that,under the diversion effect of the CB,the temperature of the cross-section of the fluid domain is distributed in a gradient,and the fluid flow shows an obvious aggregation and dispersion.When the installation directions of CB and CSETB are opposite and have the same cone angle,the outlet temperature is the highest after reaching stability,the flow velocity that impacts the stainless-steel mass block is the highest,the amplitude of the detection point is the highest,and the vibration of each CSETB in the heat exchanger is the most severe.In addition,a change in CB angle has a significant impact on the heat transfer performance of CSETB.When CB and CSETB are installed in opposite directions and have the same cone angle,the vibration-enhanced heat transfer effect and heat transfer uniformity of each CSETB are the best,and the comprehensive heat transfer capacity of the CSETB heat exchanger is the strongest.This study has good guiding significance for the design of efficient CSETB heat exchangers.关键词
