Abstract

Experiments were made on fluid flow resistance and heat transfer in theshell side of tubular heat exchangers with longitudinal flow

and the performance of heat transfer enhancement of transversally fluted tube bundle supported with the ROD tube supports was compared with that of the same tube bundle but supported with the RING tube supports. The results showed that roughness tube bundle supported with RING tube supports had better performance of heat transfer. In this paper the measurements of fluid velocity distribution made with LDV within roughness tube bundles and in the downstream direction of tube supports are given

and the influence of the forms of tube supports on heat transfer performance of tube bundles is analysed.
