“…These methods have been used to model prescribed motions of interfaces by generating meshes of varying configurations prior to the simulation (Mulholland et al , 2005; Leroyer and Visonneau, 2005). Moving overset grids (Belk and Maple, 1995; Freitas and Runnels, 1999) and adaptive unstructured grid methods (Cardoze et al , 2004) are two techniques in this class. An adaptive grid, front tracking method is used in this work.…”

A method for the computation of low Reynolds number dynamic blood cell systems is presented. The specific system of interest here is interaction between cancer cells and white blood cells in an experimental flow system. Fluid dynamics, structural mechanics, six-degree-of freedom motion control and surface biochemistry analysis components are coupled in the context of adaptive octreebased grid generation. Analytical and numerical verification of the quasi-steady assumption for the fluid mechanics is presented. The capabilities of the technique are demonstrated by presenting several three-dimensional cell system simulations, including the collision/interaction between a cancer cell and an endothelium adherent polymorphonuclear leukocyte (PMN) cell in a shear flow.

“…Then, we investigate all possible donor cells using the stencil walk [26,27] method to precisely determine whether all of them are the interpolation points' donor cells. Finally, we force the projection of wall surface's interpolation points to the curved surface whose donor cells are wall surfaces by projecting each interpolation point in the direction of the body surface's normal (see Figure 4).…”

This paper proposes an automatic structure overset grid method, which utilizes the hole-surface optimization with one-step searching, wall-surface grid oversetting, and dynamic overset grid approaches to achieve the high adaptability of overset grids for complex multi-body aircrafts. Specifically, based on the automatic structure overset grids, the method first solves the coupling of Navier-Stokes (N-S) unsteady flow equation and 6DOF motion equation, and establishes the multi-body collision model. Then, the numerical simulation of unsteady flow for complex aircrafts' multi-body separation, the simulation of multi-body separating trajectory and the separation safety analysis are accomplished. Thus, the method can properly handle practical engineering problems including the wing/drop tank separation, aircraft/mount separation, and cluster bomb projection. Experiments show that our numerical results match well with experimental results, which demonstrates the effectiveness of our methods in solving the multi-body separation problem for aircrafts with complex shapes. dynamic overset grids, multi-body separations, CFD PACS number(s): 47.85.Gj, 47.85.MCitation: Zhang H R, Fan J J, Yuan W, et al.
