Twisted Pipe Tube Heat Exchanger

(PDF) Numerical and Experimental Analysis of Heat Transfer

[Show full abstract] transient heat transfer in double tube counter flow heat exchanger was carried out with corrugations on the inner tube by twisting the pipe from one end, which gives the more

EFFECT OF TWISTED-TAPE INSERTS ON HEAT TRANSFER

twisted tape placed inside the inner test tube of the heat exchanger. Heat transfer rate of the twisted-tape inserts is found to be strongly influenced by tape-induced swirl or vortex motion. The heat transfer coefficient is found to increase by 40% with half-length twisted tape inserts when compared with plain heat exchanger. On the basis of equal mass flow Review on Twisted Tapes Heat Transfer Enhancementpresence of the tube with short-length twisted tape insert yields higher heat transfer rate. Eiamsa-ard et al. [12] mathematically investigated the swirl flow in a tube induced by loose-fit twisted tape insertion. Effects of the clearance ratio on Nu, f and g are numerically

Twisted-Tape Inserts as a strategy to improve heat

May 29, 2018 · Twisted tape enhances heat transfer in heat exchanger tubes by modifying the flow channel of the cooling fluid. In fluid dynamics, two main types of flows exist:laminar and transverse. In laminar flow, fluid particles travel in a longitudinal direction, and the only mode of
