TL;DR: In this article, the effects of the geometrical parameters and pressure drop on the heat transfer performance of a heat sink with micro-pin fin arrays were studied, and the heat flux from base of heat sink was set as 300kW/m2.

TL;DR: In this article, a two-phase three-dimensional numerical transport model based on the two-fluid method for the proton exchange membrane fuel cells (PEMFCs) with parallel flow field, interdigitated flow field and serpentine flow field has been presented to study the cell performance and transport phenomena in the PEMFC.

TL;DR: In this article, experiments were carried out to study the effects on the performances of individual cell and stack of PEM fuel cell and showed that stack performance increases with the increase in the anode humidification temperature, cell temperature, assembled torsion, and gas flow rate.

TL;DR: In this article, the effects of channel geometry and pressure drop between the entrance and exit of a liquid cooling heatsink on the heat transfer performance are studied. But the authors did not consider the effect of the height of the microchannels.

TL;DR: In this article, the effect of thermal radiation with mixed convection for a gray fluid in rectangular horizontal ducts has been numerically examined in detail, focusing on the effects of thermal buoyancy and radiative transfer on the development of temperature, the friction factor and the Nusselt number.
