Phase-averaged velocity and pressure fields in the wake of a cylinder fitted with splitter plates have been determined using a computer aided flow visualization technique and fluid forces on a cylinder have been evaluated. Some discussions of the mechanism of occurrence of the drag and the fluctuating forces have been shown. Splitter plates have an effect to modify the configurations of shedding vortices as well as one to shift the position of the vortex formation, and long vortices stretched in the flow direction are formed as the formation region shifts downstream. Either the drag or the fluctuating lift forces can be closely correlated with the velocity at a cylinder induced by the shedding vortex and the relations them is mostly linear so far as the induced velocity is small.
