Interaction of an Oscillating Flexible Plate and Nucleate Pool Boiling Vapor Bubble: Fluid-Structure Interaction in a Multimaterial Multiphase System

摘要

Many of the real world problems in engineering and science involve interactions of multiple materials and phases. The numerical modeling of such system should be able to handle the material and phase multitude to capture physics of problems. Here we present our initial results for introducing fluid-structure interaction for flexible geometries in our multimaterial multiphase fluid solver, which also captures phase change phenomena such as solidification and boiling. The multimaterial approach applies a hybrid moment of fluid and level set algorithm to handle material domains. The fluid-structure interaction method is a force-feedback algorithm developed for a flexible fiber geometry. Numerical simulations are performed to evaluate this approach, and as an application, study the effects of an oscillating flexible/rigid plate on a single-bubble nucleate pool boiling process.
