This book investigated the effect of twisted tubes on the thermal performance of the shell and tube heat exchanger. The computational fluid dynamics (CFD) with different turbulence models (realizable k-ε and standard k-ε) was employed to analyze. The results were compared with the published study to verify the present solution. In this book, mass flow rates ranging from 0.5 kg/s to 2 kg/s were considered to investigate thermal performance...
