The prism layer thickness in the solid domain is set to 0.2 mm. Ten prism layers with a stretching factor of 1.1 are used at the fluid side and five prism layers within the particle stretched by a factor of 1.5. The generated mesh consists of 2.2 million cells in the fluid and 0.4 million cells in the solid domain. To ensure a solution independent of the mesh size a mesh dependency study is carried out, which is presented in the supplementary information (SI Section S5.
