Identically similar-sized counter flow shell-and-tube exchanger with single segmental baffles and shelland-tube heat exchanger with four interstitial twisted tapes were tested with Propylene Glycol (PG) solution. Water was mixed with various amounts of Propylene glycol (0%, 20%, 30% and 40% by volume) under same operating temperature conditions. The corresponding results from these shell and tube heat exchangers were then compared. The shell and tube heat exchanger with four interstitial twisted tapes produces improved thermal enhancement index for the complete range of fluid concentrations.
