Open Questions and Suggestions for Further Research

In this final chapter, we present a number of open questions that still demand an answer. Our hope is to motivate further research devoted to the fascinating dynamics of falling film flows. We also believe that the methodology developed in Chap. 6, and applied to isothermal film flows (Chaps. 7 and 8) and to heated film flows (Chap. 9), can be extended to a wide variety of problems which have not been described in previous chapters. Some of them are discussed here.
