The main goal of this work has been to provide an initial evaluation of the potential of the modified plate type heat exchanger concept. Therefore, emphasis has been on the

In this study, computational fluid dynamics is employed to numerically evaluate heat transfer rate and pumping power ratio in a helical coiled heat exchanger by using MWCNT + Fe 3 O

Heat transfer coefficient and pressure drop were determined at saturation temperatures 0, 5 and 10 °C for the smooth tube, while the three tubes were compared at heat fluxes

The comparison showed that the novel analysis resulted in lower net power output than the thermodynamic analyses due to working fluid-depending pressure drop in heat exchangers, and

The spacers influence the performances of the MEE: they can enhance heat and moisture transfer, resulting in higher effectiveness, but they also increase pressure drop, resulting
