摘要: The problem of the resolution turbulent flows in adaptive mesh refinement (AMR) simulations is investigated by means three-dimensional (3D) hydrodynamical an idealized setup, representing a moving subcluster during merger event. AMR performed with usual criteria based on local gradients selected variables do not properly resolve production turbulence downstream cluster. Therefore, we apply novel which are optimised to follow evolution flow. We demonstrate that these provide better flow past subcluster, allowing us onset shear instability, wake and subsequent back-reaction core morphology. discuss some implications for modelling cluster cold fronts.
