An Efficient, High-order, Adaptive Finite Volume Solver for Modelling Capillary Effects in Advanced Manufacturing Processes
share
We present a free and open source implementation of the Finite Volume Method that captures thermal and solute-driven free-surface flows, more commonly known as Marangoni flows. This type of physics commonly appears within many manufacturing processes as well as microfluidic devices and is known to be challenging to resolve. The application includes adaptive mesh refinement and high order WENO schemes in order to substantially save computational cost in multiphase flows where adequate tracking of the phase boundaries is crucial. By accurately simulating the temporal evolution of multiphase flow patterns, unique insight into e.g. the physics of melt pool formation in metal additive manufacturing is possible that is otherwise hard to gain experimentally. We demonstrate our work by a simple two-dimensional benchmark case and outline possible applications with a mesoscopic model of Laser Powder Bed Fusion additive manufacturing.
