Evaluation of thermal performance factor by hybrid nanofluid and twisted tape inserts in heat exchanger
Noor Fouad. A. Hamza, Sattar Aljabair
Abstract
%) and Reynolds number (8320) is about (1.068), when the plain twisted tape and double v-cut twisted tape inserted with hybrid nanofluid the thermal performance factor increased to (1.33) and (1.37), respectively. The results show a similar trend for both numerical and experimental cases. The comparison between the experimental and numerical results have maximum error was (9.7)%.
