Abstract
In this study, Dual-camera system with two high speed cameras is applied to the flow field around a bubble and verified. Dual-camera system is to acquire images from two high speed cameras which record the same viewing field. A viewing field of these cameras corresponded by using both a calibration target and micro motion positioning stages. In PIV used CW laser, a time interval of two images depends on the camera frame rate. A time interval of two images affects the measurement accuracy significantly. Therefore, it is important to control a time interval of two images. This developed technique provides an arbitrary interval of two images by delaying capture timing of slave camera. Capture timing was controlled by phase shift function generator. Eventually, we measured surrounding liquid motion in the vicinity of the bubble to examine availability of this method.
