From comparison of the approximate solutions with the numerical one, it is concluded that one kind of averaging approach in which some of the time dependent terms are treated exactly while the convective inertia terms are averaged out across the film thickness gives close approximations in a wide range of desigining conditions, and that an other kind of averaging approach in which all the inertia terms including the time dependent terms are averaged out across the film thickness is a fairly good approximation.
