The channel width is typically 5 to 10 cm in laboratory experiments and its height is 3 m. The soap film is between 2 to 6 µm thick and travels between 0.5 and 4 m/s, depending on the fluid injection rate. The soap film channel width is in general 10 or 10 times wider than the film thickness. The flow is therefore expected to be two-dimensional for all practical purposes. Color Particle Image Velocimetry is inherently a two-dimensional method hence it is ideally suited for the soap film flow measurements. The CPIV method invokes color CCD camera to record different color, multi-exposure particle images on a single frame. The time interval between exposures can be specified as required. A multi-color particle image can be easily separated into unique color, sequential images. Both the magnitude and direction of the velocity vectors can be determined from the unique color, sequential particle images using cross correlation analysis. A series of flow past circular cylinder, such as flow past double circular cylinders, flow past circular cylinder in confined channel flows, etc., were investigated. Very detailed velocity and pressure distributions for these ideal two-dimensional fluid motions were obtained.
