| description | Particle image velocimetry is a method for the visualization and measurement of fluid flow which is one of the major methods in the study of fluid . In most applications of PIV , tracer particle or seeder particle needs to be added to the stream . For liquid flow , in general seeding is done with the suspension of solid particles into the flow and mixed in such a way as to obtain a homogeneous mixture . The problems that arise with the use of solid particles such as SiO2 and aluminum flakes as this is the provision of particles is high enough cost and environmental pollution caused by the disposal of liquid and particles that are not used . By using microbubble tracer instead of a solid particle , a negative effect on the environment can be avoided . In addition, the size can be adjusted easily with a combination of pressure and flow in the Micro - Bubble Generator . Micro - Bubble Generator which is used is the type of orifice with a diameter of 4 mm. In this study, micro - bubbles generated inside a chamber , and for the next micro - bubble into the main flow direction of the horizontal pipe by itself due to the force of gravity . The main flow pipe wear acrylic material with the aim to facilitate the process of observation . Data were drawn from this study is the Stokes number and relaxation time . Data obtained with several variations of the water capacity and air capacity is automatically entered into the Micro - Bubble Generator . Water capacity and air capacity varied 11 L / min - 14 L / min and 0.3 L / min - 0.87 L / min . For equipment using LED lighting sources and compared with the 532 nm diode laser with an output power of 200 mW . With these two sources of illumination , can do a comparison between Laser Diode LED with issues related to the effectiveness of the visualization . This study aims to develop and make seeder mechanism combined with microbubble generator as a source of tracer and find the optimum microbubble size for PIV observations . Keywords : microbubble , seeding particles , tracer , Particle image velocimetry , LED , Laser Diode , Stokes Number, Relaxation Time |
