This approach can evaluate the inertia effects under highly unsteady conditions. Compared with this, the accuracy of the approximate solutions presented in the previous report is evaluated under such conditions and the following conclusions are obtained: (1) The conventional averaging approach in which all the inertia terms are averaged out across the film thickness gives a fairly good approximation. (2) The first-order solution of the perturbation method becomes remarkably inaccurate as the unsteadiness becomes high.
