Droplet evaporation model (Dukowicz)

student

Hi all. I am trying to write down the equations for the Dukowicz evaporation model (Lagrangian spray modeling), but I cannot find neither the original paper

J. K. Dukowicz. Quasi-steady droplet phase-change in the presence of convection. Technical Report LA-7997-MS, Los Alamos Scientific Laboratory, aug 1979.

nor any other complete description. Does anybody know where can I find the description?

My problem is in writing the vapor gradient to temperature gradient ratio at the droplet surface, as a function of the surface and undisturbed flow conditions (enthalpies and mass fractions for air and vapor). It should be derived from species and energy conservation equations, but how?

Thanks in advance.
