Web(STHXsHB) can effectively reduce flow resistance, weaken the vibration of the tube bundle, prevent shell- side fouling, and markedly increase heat transfer coeffi- WebThe theory of entransy dissipation was employed to evaluate the irreversible loss in STHXsHB with different helix angles and overlap proportions. The results indicated that both the baffle overlap proportion and the helix angle have a great effect on the shell-side flow resistance and heat transfer. free childcare for 3 year olds eligibility
