In the dissertation, the patched grids which are generally used in the structured grid are introduced to generate unstructured dynamic grid which can be used to solve complex unsteady flow around rotational boundary.

METHODS: Eighteen healthy male military pilots were tested by mental rotation test and their reaction time (RT) were measured and compared under six-condition matrix composed of 3 planes (the traverse plane, the sagittal plane and the coronal plane) and 2 tasks (viewer rotation and array rotation).
