The research focuses on spray cooling for electronics cooling applications, with particular emphasis on intermittent spray cooling. Using an IR camera, the transient surface temperature response under varying pulsed spray conditions is analyzed. The investigations examine how duty cycle, pulse frequency, spray flow rate, and surface properties influence cooling performance, temperature uniformity, and heat flux removal. Detailed spray characterization by measuring droplet size distributions and spray velocities to correlate spray parameters with cooling effectiveness will be performed. In addition, numerical modeling of sprays is employed to simulate fluid flow, droplet evaporation, and heat transfer, comparing simulation predictions with experimental data. The work aims to manage high heat fluxes in compact electronic systems while improving energy efficiency through optimal control of spray parameters.
