A modular procedure is presented to simulate moving control surfaces within an overset grid environment using the Navier-Stokes equations. Gaps are modeled by locally shearing the wing grids instead of using separate grids to model gaps. Grid movements for control surfaces are defined through a separate module, which is driven by an external grid generation tool. Results are demonstrated for a ...

In recent years, much attention has been given to domain decomposition methods for solving linear elliptic problems that are based on a partitioning of the domain of the physical problem. More recently, a new class of Schwarz methods known as optimized Schwarz methods was introduced to improve the performance of the classical Schwarz methods. In this paper, we investigate the performance of thi...

In actual engineering, asymmetric flow often occurs, but rigid partitions are installed in the direction of field and symmetric direction. This will result a deflection angle between dividing plate incoming flow. The research results show that when declination is low, partition has limited impact on system; about 10 degrees, system vibration characteristics have abrupt changes, amplitude decrea...

Overset grids resolve complicated geometries by creating high quality structured grids that are independently built for each component. This simplifies the process of grid generation, but domain connectivity must be performed so that adjacent grids share information. Shortcomings of the current X-rays method for the hole-cutting step of domain connectivity were explored to automate the X-rays a...
