title = "An Oil-Jet Cooling Design for Electrical Machine End Winding: Distribution of Oil and Oil Droplet Studies",
abstract = "Effective thermal management is essential for advancing transportation electrification. Oil-jet cooling offers efficient, direct heat removal in electric machines, supporting compact and high-performance designs. However, limited experimental data on oil droplet behavior pose challenges for optimizing cooling effectiveness and validating simulation models. To address this gap, this study develops a custom-designed oil-jet test rig for electric machines. Using high-speed imaging, droplet size and dynamics are captured at scales down to 110 μ m. The resulting measurements and distributions reveal the complex mechanisms of oil-jet cooling, providing a physical basis for understanding heat transfer processes. These findings will serve as guidelines for future simulation work and enable the derivation of formulas to evaluate oil-jet cooling performance.",
