Abstract
A new, non-intrusive method is proposed to measure the solid-liquid contact temperature duringdropwise evaporative cooling. The droplets are deposited onto a material which is transparentin the infrared spectral band. The interface temperature can thus be measured through the solidmaterial by a thermographic camera. The transparent tile is coated with a very thin layer ofhigh-emissivity, opaque paint on its upper side, so that it can effectively respond to the infraredcamera below.
