Two case studies are presented in this chapter for measurement of filmwise and dropwise mode of condensation heat transfer to demonstrate its efficiency. Use of inverse heat transfer technique for well-designed experiments is fo

The model is validated against controlled laboratory experiments for sessile droplet evaporation of water on copper and glass substrates that offer distinct wettability. The study reveals the limitations of the vapor diffusion model and the importance of additional mechan

H. Burkhard Dick,Oliver Schwenn The significance of droplet level details including statics, spreading, and coalescence is revealed in the text. Additional discussion related to surface preparation and measurement of heat fluxes on the drop-scale and the device-scale are presented. This final chapter closes with newer directions

Spreading of Sessile and Pendant Drops on Partially Wetting Surfacesycerin drops over fully and partially wetting surfaces is studied in terms of excess pressure, wall shear stress, and the footprint radius. Water drops show oscillations during spreading while glycerin spreads uniformly over the surface. The mathematical model also predicts heat transfer rates from

Scale analysis in terms of force pairs and energy components delineate experimental trends in velocity and wall shear stress. Shear stresses are momentarily developed at the wall at the short timescale, with a magnitude depe
