Webbaffle cuts are detrimental to efficient heat transfer on the shell side as they create vortices inside the shell. And baffle cuts ranging from 20% to 36% are considered as very efficient [2]. Baffles may be classified as transverse and longitudinal types (for example, the F-shell has a longitudinal baffle). WebThe optimum ratio of the overall heat transfer coefficient to pressure drop was found between baffle spacing of 203.2 and 304.8 mm, which are ranged between 0.43 and …
