Abstract
The present paper aimed to conduct an experimental study on the hydro-thermodynamic performance of the double-tube heat exchanger using the water-magnesium oxide nanofluid and double twisted tape with three different steps (3.5,5and7 cm).The experiments were performed in the turbulent flow for the Reynolds numbers from 4400 to 16000 and the nanofluid volume fractions of 0.7%and 1.0%.The results were obtained at different flow rates with or without the use of twisted tape and nanofluid designed and manufactured in the experimental setup to calculate the convection heat transfer coefficient.Also the effect of using double twisted tapes at three steps along with the magnesium oxide nanofluid was greater in the higher Reynolds numbers.In the Reynolds numbers 4400,the convection heat transfer coefficient increased about17%for the volume fraction of0.7%and about 29% for the volume fraction of 1%.Also in the Reynolds number of 16000,it increased about48%for the volume fraction of 0.7% and about53% for the volume fraction of 1%.The simultaneous use of magnesium oxide nanofluid and double twisted tapes with the step of 3.5 cm in the Reynolds number 6400 was more effective than deionized water compared to other results.The performance evaluation criteria were examined in all cases and in case of using nanofluid and twisted tape with the step size of 3.5 cm, the highest value of the performance evaluation criterion is obtained with80% increase compared to the base state.
