High-order modeling of interface interactions using level sets

Abstract

Most technological advancements in medicine, process and energy engineering, life and food science, mobility and environmental engineering involve mastering fluid mechanical effects. In particular, compressible flow physics including shockwaves and phase-interface interactions exhibit multi-scale phenomena spanning several orders of magnitude upwards from nanometer and nanosecond time scales. Clearly, detailed analysis of such effects is impossible by means of experimental techniques. On the contrary, numerical modeling and simulations allow to capture the aforementioned mechanisms and provide non-invasive access to any quantity of interest. Yet, the complex fluid physics require powerful computational methods utilizing recent advancements for high-order schemes. In this work, we provide an overview on latest high-order low-dissipation schemes using level sets to model discontinuous phase-interface interactions.
