Abstract
This paper describes the experimental study of the characteristics of a non-contact type suction device using Coanda effect. The present study has been carried out for flow analysis around a non-contact suction device. The main aim was to obtain the useful data for CFD analysis by suitable visualization. TiO_2 particle shows the difference of the flow pattern around the non-contact suction device with work and without work well. It is found that the range of the flow velocity is too wide to fix the suitable photography condition. Constant Temperature Anemometer (CTA) is also applied to measure the flow velocity. The strong turbulence of air flow is observed around the non-contact suction device.
