Özet

In recent years, it is a topic that has been discovered in the field of electrospray cooling, which is used in many areas in industry. In this study, the cooling performance of electrospray cooling and mechanical spray cooling on the heat sink, about which there are very limited studies in the literature, were examined. In the same conditions, the data of heat transfer with electrospray were obtained by conducting experiments, while the data of mechanical spray cooling were obtained by using Ansys Fluent CFD program. As a result of the experimental and numerical study, it was determined that electrospray cooling, in which smaller particle diameter and charged droplets were obtained, showed a heat transfer performance approximately 15% better than mechanical spray cooling. In the electrospray method, it was observed that 13% better cooling was obtained at 3,2 kW/m(2) heat flux, at 2,59 kW/m(2) heat flux %14 and better at 1,88 kW/m(2) heat flux %17 compared to mechanical spray.
