Experimental investigation and performance analysis of triple concentric helical tube heat exchanger
نویسندگان
چکیده
An experimental investigation for helical triple concentric tube heat exchanger has been carried out with different flow arrangements i.e. N-H-C (normal fluid inside hot at middle cold in outer annulus) and C-H-N (cold fluid in inner pipe hot in middle normal fluid in outer annulus) with parallel and counter flow types. The temperature distribution of fluids w.r.t. length of the heat exchanger has been observed. Effectiveness is calculated for parallel and counter flow in NHC and CHN arrangements. The triple concentric helical tube heat exchanger proved to be effective and of compact design for heat exchange between the fluids. The N-H-C counter flow arrangement with high volume flow rate of fluid proved to be effective than other arrangements.

In this study, the thermal characteristics of turbulent nanofluid flow in a helical tube in the tube heat exchanger (HTTHE) were assessed numerically through computational fluid dynamics (CFD) simulation. The findings of both the turbulent models: realizable k-epsion (k-ε) and re-normalisation group (RNG) k-epsilon were compared. The temperature distribution contours show that realizable and RN...
