AB On the basis of a standard one-sided lubrication-type model,   an analysis is carried out pertaining to a small vicinity of a contact line of   a volatile nonpolar perfectly wetting macroscopic liquid sample surrounded   with its pure vapor and attached to a smooth uniformly superheated solid   surface.  The  behavior  of  the  liquid  film  is  governed  by  the  effects  of   evaporation, capillarity, and the disjoining pressure. The kinetic resistance to   evaporation, as well as the dependence of the local saturation temperature   on the local liquid pressure are accounted for. Within the localized approach   pursued,  a  steady  configuration  of  the  film  on  a  flat  substrate  is  studied   such that at one end (say, to the left) it asymptotically attains an adsorbed   microfilm  in  equilibrium  with  the  vapor,  while  to  the  right  it  gets  on   to  a  constant  slope  (contact  angle  of  the  "microstructure").  For  moving   contact lines in the situations like drop spreading or bubble growth in the   boiling  process,  this  microstructure  is  relevant  in  the  quasi-steady  sense,   provided that the displacement velocity is not too large. The paper focuses   on  a  numerically  based  parametric  study  expressing  the  contact  angle   and evaporation flux characteristics as functions of the system parameters.   Asymptotic  expansions  at  both  ends  of  the  film  are  elaborated  in  some   detail and relied on in the numerics. Asymptotic results from the literature   involving  certain  limiting  cases  of  the  system  parameters  are  critically   examined. At last, the Marangoni and the vapor-recoil effects are additionally   incorporated and their possible importance is assessed.
