Least-squares fitting was employed to interpolate the reflect point, ghost body-cell method (GBCM) was applied to quadtree-based adaptively refined Cartesian grid approach, and finite volume method was employed to solve Euler equations. Shape of cut cell kept in accordance with that in the flow field which efficiently relieved the time step restriction of small cut cells. Flows around a circular cylinder and the double NACA0012 airfoils are simulated and compared with published structured grid results, which show flow field around complex geometries is adequately resolved resort to GBCM approach on adaptively refined Cartesian grid in computational fluid dynamics (CFD).
