An numerical grid generation method is utilised to construct a grid system which is aligned with the interface. The computations are restricted to two-dimensional incompressible and laminar flow which are described in axisymmetrical coordinates. Future directions for investigation of physics of film boiling process include experimental validation of the numerical results. High speed digital photography is being used to study the effect of subcooling on growth process of Taylor instability in film boiling. This is the first attempt of its kind in the investigation of physics of subcooled film boiling on a flat plate under pool boiling conditions.
Water is used as the working fluid.
Mechanistic model for subcooled boiling based on the above database will be developed. Flow visualization experiments are being performed in a plate fin heat exchanger with freon 134A and air. The purpose of the experiment is to study the formation of the vapor front at different flow rates. The study is aimed at investigating the properties of the thin layer of liquid water on a solid surface using Molecular Dynamics simulations. Surface tension of thin liquid film will be studied as a variation of thickness of the film.
