TL;DR: In this paper, the effects of the time-mean jet Reynolds number, temperature difference between the jet flow and the impinging surface, nozzle-to-target distance as well as the frequency on heat and mass transfer were examined.

TL;DR: In this article, a numerical investigation was performed to study the effect of flow pulsations on the time-averaged Nusselt number under a laminar impinging jet.

TL;DR: In this article, a numerical investigation has been performed on a two dimensional pulsed turbulent impinging jet under large temperature differences between the jet flow and the impinging surface to examine the effect of temperature-dependent thermophysical properties along with pulsation of the jet on the local Nusselt number distribution on the target surface.

TL;DR: In this article, a computational fluid dynamic simulation of the flow and heat transfer characteristics of a single axis-symmetric semi-confined laminar jet impinging normally on a plane wall is presented for purely viscous power law fluids.

TL;DR: In this article, a flow structure which delivers the reactant transversely to the MEA using an impinging jet configuration at cathode side is proposed and modeled to examine its effectiveness for enhanced PEMFC performance, especially at high current densities.
