Outline of Final Research Achievements

Combination of optical thermometry using the two photon absorption and time domain thermoreflectance was utilized to capture the dynamics of surface temperature and interfacial thermal resistance between droplet and heated substrate. This helped to better understand the underlying physics at high frequency rates to develop a phase diagram for the droplet impingement studies based on Weber number.
