Abstract: A simultaneous measurement system that can analyze the flow
structure interactions has been developed. This system consists of four CCD
camerasm, two for capturing instantaneous flow fields and two for tracking a
solid body. The three dimensional vector fields around a cylinder are measured
while the motion of the cylinder forced by the flow field is measured
simultaneously with the constructed system. The cylinder is suspended in the
circulating water channel and the surface of the working fluid is forced
sinusoidal to make the cylinder bounced. Reynolds number for the mean main
stream is about 3500. The interaction between the flow fields and the cylinder
motion is examined quantitatively.
