Experimental study on the interfacial heat transfer of sessile droplet evaporation using temperature-sensitive paint

•The contact line profile captured by TSP is consistent with that by an infrared camera.•Three stages could be observed during sessile droplet evaporation on a heated substrate.•The occurrence of convection cells leads to obvious temperature gradient on interface.•The heat flux at the contact line i...
