Towards a generalised dual-mesh hybrid LES/RANS framework with improved consistency

•Dual-mesh hybrid LES/RANS framework solves LES and RANS equations on separate grids.•Coupling of grids is refined to improve consistency between RANS and LES solutions.•Automatic computation of RANS/LES interface location and relaxation time-scales.•An elliptic blending eddy viscosity model is used...
