Etude Experimentale D'un Echangeur De Chaleur A Triple Tube Concentrique Pour Differents Arrangements
Résumé: Heat exchangers are devices used for heat transfer between different fluids. These heat exchanges differ according to the field of application. The main objective of this work is the thermal design and the realization of a heat exchanger. Thus, a concentric triple-tube heat exchanger is made on the basis of a similar experimental study previously proposed by the University of Biskra team. This realization allowed the study of the effect of the flow on the efficiency (performances) of the exchanger in the four possible configurations; Co-current, counter-current, co-current / countercurrent and countercurrent / co-current. The results showed that the countercurrent arrangement is the most efficient and that the efficiency is even better when the working fluid circulates in the internal annular tube. Key words: Heat exchangers, triple concentric tube heat exchanger, different arrangements
