Effectively Design Shell-and-Tube Heat Exchangers
Hermal design of shell-and-tube heat exchangers (STHEs) is done by sophisticated computer software. However, a good un- tions for tubeside and shellside heat transfer and pressure drop are well-known; here we focus on the application of these correlations for the optimum de- ...
