Computational Modelling of a Spanning Drop in a Wedge with Variable Angle

Abstract

This work has undergone a double-blind review by a minimum of two faculty members from institutions of higher learning from around the world. The faculty reviewers have expertise in disciplines closely related to those represented by this work. If possible, the work was also reviewed by undergraduates in collaboration with the faculty reviewers. AbstractIn this work, mathematical and computational techniques were used to model the phenomenon of a bubble or liquid drop as it slides to the narrowest side between two tilted plates. Practical applications of this phenomenon, such as the adjustment of liquid propellant tanks, are also discussed. Computations involved the use of Surface Evolver-a fully open, interactive program that allows the simulation of physical experiments in a virtual environment.

An Evolver program for weighted Steiner trees

“…With Evolver physical experiments can be performed in a completely virtual environment, and one can easily add complexity to the model, or even adapt it for further developments. Firstly introduced in 1989, now Evolver's most recent version is 2.70 [8] with several applications in many Areas of Knowledge like Aerodynamics [9], Fluid Dynamics [10,11,12] and Medicine [13]. Furthermore, Evolver is endowed with several built-in energy minimisation routines which enable saving a lot of programming by just invoking them.…”
