Sažetak
In the paper, influence of segmental baffles on heat transfer and pressure drop in countercurrent water-water shell-and-tube heat exchanger has been numerically investigated by comparing two heat exchanger configurations ; with and without baffles, for equivalent operating conditions. Six panels are used as baffles, to divert the shell-side fluid flow and to increase heat transfer. Computational domain has been divided into three subdomains ; hot water, cold water and wall subdomains and mathematical model has been defined. A standard k-ε turbulent flow model was used since Reynolds numbers are greater than critical values for investigated operating conditions. Four cases with different shell-side flow rates have been analyzed for both heat exchanger configurations. Hot and cold water temperature distributions throughout the domain, as well as velocity vectors, have been presented. Heat fluxes on both hot and cold water side have been calculated for all cases. Additionally, pressure drops have been numerically calculated for analyzed cases and configurations. It is observed that higher heat fluxes, but also the higher pressure drops, are achieved for the configuration with baffles.
