A detailed numerical investigation of the effects of support fibers on the vaporization of a fiber-supported droplet in reduced gravity is presented. The volume-of-fluid (VOF) method was employed to capture the liquid-gas interface while allowing for time-dependent two-phase multidimensional flows. The calculations allowed for the inclusion of thermocapillary stresses at the liquid-gas interface. The study also investigated the effects of the thickness of fiber, ambient pressure, and ambient temperature on droplet evaporation. The present computational results agree well with experimental results.
