Abstract

Shell side heat transfer and flow resistance characteristics of the spiral elliptical tube heat exchanger and smooth tube heat exchanger with segmental baffle were investigated using CFD method. Basing on this investigation, the appropriate applications of spiral elliptical tube heat exchangers were analyzed. The results showed the spiral elliptical tube has no effect on shell side heat transfer enhancement, however the shell side flow resistance of a spiral elliptical tube exchanger is far less than that of a smooth tube heat exchanger with segmental baffle and the comprehensive performance is much better than the latter. The spiral elliptical tube heat exchanger is more suitable for the cases of large fluid flow rate, high pressure drop, fluid easy scaling and easy to induce bundle vibration on shell side.
