  • Abstract:
  • The effects of V-nozzle inserts on heat transfer and friction characteristics in a single tube heat exchanger has been experimentally studied. The v-nozzle with pitch ratio 6.0 used. Experimental investigations have been carried out to study the effects of the V-nozzle turbulators on heat transfer augumentation, friction 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 130% over the plain tube. A maximum gain of 1.23 on enhancement efficiency is obtained for the pitch ratio used, PR=6.0. This indicates that the effect of the reverse/re-circulation flows can improve the heat transfer rate in the tube. In addition, correlations from the results are presented and Reynolds number ranging from 8000 – 35000 experimentally.
