An Experimental Study on a Flow in Wall Attachment Fluidic Devices

Many theoretical and experimental studies on attached flow in fluidic logic elements have been made, but these are described of simple model without splitter. In fact, however, it is necessary to know the characteristics of internal flow of elements with splitter, so we have tried an experimental study by large scale model with splitter. In this study, maximum pressure point is determined from static pressure distribution on side wall and attached point length is measured. The visualization of internal flow is accomplished by photograph using piece of synthetic resin.
