A finite volume method in unstructured grid system is developed for the study on complicated two-dimensional low Reynolds number flows. The numerical method is first validated by a cavity flow problem, and then applied to some problems such as a surface flow accelerator and a rotating body problem which would be difficult to solve by a structured grid. A moving grid system is introduced and applied to an unsteady problem. The developed moving grid system makes it possible to change the grid fast to fit a moving body at every time step without any regeneration of grid. The present computations show the possibilities of applying the developed technique to the analysis of flows around multiple moving bodies.
