This project presents theoretical, computational, and experimental
aspects of mass-loss of fluid drops due to evaporation. The
theoretical component consists of using basic principles such as
conservation of mass, momentum, and energy together with an
evaporation model to derive an evolution equation for a fluid drop.
This equation is solved and analyzed for comparison with the
experimental results for fluids such as water, 70% and 100%
isopropyl alcohol. Experiments were performed using a professional
grade goniometer which allowed us to precisely measure contact angle
and volume as a function of time. The comparison between
computational results and experimental results is focused on the
change in volume, mass, and contact angle. In addition, we show
curious instabilities which developed for 100% isopropyl alcohol
drops.
