Local heat transfer to an evaporating superhydrophobic droplet

The heat flux distribution beneath a superhydrophobic evaporating droplet has been explored. High speed, high resolution infrared thermography was employed to measure the heat transfer characteristics of the evaporating droplet. Optical imaging and analytical techniques were used the capture droplet dynamics over the course of its evaporation. The droplet evaporated with a receding contact line predominantly in the constant contact angle …
