Abstract

The effects of V-nozzle inserts on heat transfer and friction characteristics in a uniform heat flux tube are experimentally and numerically studied. The v-nozzle with pitch ratio 2.5 used. Experimental investigations have been carried out to study the effects of the V-nozzle turbulators on heat transfer augmentation, friction characteristics and enhancement efficiency, in a circular tube. It is found that using the V-nozzle can help to increase considerably the heat transfer rate at about 107% over the plain tube. A maximum gain of1.25 on enhancement efficiency is obtained for the pitch ratio used, PR=2.5 this indicates that the effect of the reverse/re-circulation flows can improve the heat transfer rate in the tube. Experimental error recorded is 2.8% for friction factor when it’s compared with Numerical result at the same Reynold No. In addition, correlations from the results are
