N2 - Experimental and theoretical studies of evaporating droplets of relatively large volume are conducted. Two numerical models are presented and their predictions are discussed in detail. Experiments on droplet evaporation on two substrates of the same chemical composition but different degrees of roughness, produced by spray Teflon and spin Teflon on glass, were conducted with the objective of understanding the effect of roughness and contact angle hysteresis. The influence of the substrate temperature was investigated, showing much faster evaporation for higher temperatures. Droplets under similar conditions were then studied on a more thermally conductive stainless steel substrate, such that the effects of substrate conductivity could be investigated.
