The Flow around an Oscillating Flat Plate with Splitter in Stationary Fluid : Numerical Analysis by Discrete Vortex Model

It is very interesting to examine fluid forces on an oscillating bluff body with splitter plates in stationary fluid in connection with wave-induced forces on ocean structures and others. The discrete vortex model together with the conformal mapping method has been a;;lied to analyze the flow around an oscillating flat plate with splitter plates in a stationary fluid. Numerical calculations are performed for different splitter lengths and inclined angles of plates in various oscillating conditions, and vortex patterns and unsteady forces are obtained. From the calculations, it has been found that the splitter prevents the development of the shedding vortices and that the forces on the plate are influenced by the splitter length and inclined angle remarkably.
