Study of Contact Line Parameters of Evaporating Sessile Drops from Various Substrates

The entire process of evaporation is described by diffusion, convection, and various equations of heat transfer that simultaneously influence the process and hence, make it a complex phenomenon. The varying evaporation rate of a drop of liquid from the surface of a solid substrate is a function of the diffusion rate of vapor into the medium surrounding the droplet. The evaporation of a liquid is a naturally occurring phenomenon. If the immediate vicinity is not saturated with liquid-vapor, the liquid drops evaporate over time. The dimensions of the droplet are expressed to have a functional relationship with time. Also, the effect of drop parameters on different tribologically engineered substrates is observed with time.
