TL;DR: In this paper, a pulsed-spray water cooling system is designed for photovoltaic panels to improve the efficiency of these solar systems and decrease the water consumption during the cooling process.

TL;DR: In this article, a numerical study was conducted to seek an optimized arrangement of steady and pulsating impinging multiple submerged slot jets, and a composite design consisting of steady as well as intermittent (on/off) or sinusoidal jets in different combinations of four slot jets was simulated.

TL;DR: In this article, the authors analyzed the flow and heat transfer characteristics of an impinging jet on a concave surface at small jet-to-surface distances at small Reynolds numbers.

TL;DR: In this paper, the effect of elliptical pin-fins on heat transfer enhancement from a concave surface has been investigated, and the results reveal that applying the elliptical pins can effectively enhance the heat transfer rate from the concave surfaces.

TL;DR: In this paper, a sinusoidal pulsation is superposed on the mean velocity for normal impingement on the two-dimensional asymmetric concave surface and the RNG k-e is employed to model the turbulent behavior of the flow and heat transfer.
