文摘
Grid refinement study is performed for 3D CFD model with rotating object. Numerical uncertainty of CFD model of the Dethridge wheel is quantified using GCI. Assessing uncertainty on 3D model with moving object is computationally intensive. The small values of GCI indicate the reduced dependency of results on cell size.
