On the Validity of Two-Dimensional Heat Transfer Simulation of Moving Droplets Between Parallel Plates

Use of moving droplets between two parallel plates has been investigated widely in recent years for cooling purposes. While the real shape of the droplets is a cylinder with curved side (convex or concave) i.e. a three dimensional shape, most of the researchers assumed a two-dimensional computational domain including vertical mid plane of the droplet, which is applicable for not realistic long droplets. In this paper, the differences between these two approaches are investigated numerically, using ANSYS Fluent package.
