Abstract


The  heating  and  evaporation  of  single  component  spherical  and  spheroidal  drops  in  gaseous  quiescentenvironment are predicted, accounting for the effect of a non-uniform distribution of the temperature at the drop surface. The analytical solution of the species conservation equations in the proper coordinate system (spherical/spheroidal) is implemented to numerically solve the energy equation in a rectangular domain. The effect  of  temperature  disuniformity  on  the  local  Nusset  number  and  global  heat  and  evaporation  rates  iscalculated for different species, drop deformation and gaseous temperature.
