Abstract

Present Experimental work shows result obtain from experimentation of heat transfer enhancement in circular horizontal tube by using clockwise and counterclockwise corrugated twisted tape inserts with working fluid is air. Experiments conducted on plain circular tube with or without c-cc corrugated twisted tube. During experiment constant heat flux and different mass flow rate condition. The c-cc corrugated twisted tape are of same pitch and twist ratio but three different angle of rotation in clockwise and counter clockwise direction as 30 ?, 60 ?, 90 ? respectively. The Reynolds no. varied from 4000 to 10000. Heat transfer coefficient and pressure drop are calculated and results are compared with the plain tube without inserts. Finally heat transfer enhances with clockwise and counterclockwise corrugated twisted tape inserts as compared to plain tube varied from 8 % to 44 % for various inserts.Plain twisted tape results are also compared with the same results.
