“…Most popular approaches preserve the classical body-fitted (BF) meshes, requiring boundary nodes to coincide with the obstacle surface. For instance, mesh deformation method, based on quasi one-dimensional elastic media [6], is the least computationally expensive body-fitted approach, which allows efficient deformation of the computational mesh governed by the body motion. The main disadvantage of the mesh deformation method is its inability to handle large obstacle displacements leading to mesh deterioration and/or entanglement.…”

A novel hybrid dynamic mesh redistribution -immersed boundary method for simulation of turbulent flows around rotating obstacles of complex geometry and analysis of tonal acoustics is proposed. The feasibility of the approach is demonstrated by considering a drone propeller problem. The results of three-dimensional Reynolds-averaged Navier-Stokes simulations using the proposed approach are compared to the results of body-fitted unstructured simulations in noninertial reference frame. The dynamic mesh redistribution method allows the reposition of mesh points taking into account the shape of the moving body while retaining the mesh topology. The cell size and quality of the dynamically redistributed mesh strongly depend on the curvature of the body surface. The position and shape of the moving obstacle is prescribed by a distance function defined on an adaptive octree. The results of simulations using the proposed method are in good agreement with both the results of body-fitted simulations and the experimental data.
