TITLE
  DISPLAY
  Evaporation of a particle with conditions such that
  the particle temperature is constant.
  Constant gas temperature,no slip.
  Particle diameter as a function of time is given by:
 
  d = sqrt(d0**2 - 4.Nu.kg(Tg-Tp).t/rhop/L)
 
  where: d    - particle diameter
         d0   - particle initial diameter
         kg   - thermal conductivity of continuous phase
         L    - latent heat of evaporation
         Nu   - Nusselt number
         t    - time
         rhop - particle liquid density
         Tg   - gas temperature
         Tp   - particle temperature
