Flow over periodic hills – Numerical and experimental study in a wide range of Reynolds numbers
TL;DR: In this article, a detailed analysis of the flow over smoothly contoured constrictions in a plane channel is presented, which is a generic case of a flow separating from a curved surface with well-defined flow conditions.

High‐order stable interpolations for immersed boundary methods
TL;DR: In this article, the analysis and improvement of an immersed boundary method (IBM) for simulating turbulent flows over complex geometries are presented. Butler et al. proposed a method to interpolate boundary conditions from the solid body to the Cartesian mesh on which the computation is performed.
