In this work, we cast multiple splittings into a common framework, which makes it possible to compare them numerically. Temporal discretization is done with IMEX Runge-Kutta methods, while for the spatial part, we rely on the discontinuous Galerkin spectral element method. It is shown that, while the influence of the splitting on accuracy is small, it has a large impact on efficiency. | Keywords: | Droplet dynamics;Sprays;DIPSI;Gas Interactions;Wall Interactions | Document URI: | http://hdl.handle.net/1942/31024 | ISBN: | 9783030333379 | DOI: | https://doi.org/10.1007/978-3-030-33338-6_4 | Rights: | Springer Nature Switzerland AG 2020 | Category: | C1 | Type: | Proceedings Paper | Validations: | vabb 2024 |
