Laminar Flow Visualization Channel: table is used to illustrate the streamlines around drag bodies. The unit uses water as the flow medium. A contrast medium (dye) is injected through small needles into the flow area. Various drag bodies (included) can be placed in the area of flow. In addition, sources and sinks can be simulated and illustrated using eight additional openings in the flow area. The setup consists of a flow channel made of Fiber Reinforced Plastic (FRP) with the inlet, outlet tanks. The flow channel is formed between the two tanks. Water enters through the inlet connection into the inlet tank & flows through the flow channel into the outlet tank. To regulate the flow rate of water, valves are provided in the inlet & outlet line of the flow table. The flow section consists of a base plate made of transparent plastic. A glass plate is used to cover the base plate with a 3 mm space between the two. The upper glass plate can be lifted & secured by chains so that different models can be put in the flow channel. Water flows through space between two plates into the outlet tank. The dye is injected through a set of needles into the flow section & can be visualized with ease. The dye is contained in a vessel fitted with a valve to adjust the flow rate of dye. The apparatus is supplied with bodies of different shapes made from thin plastic. These shapes include cylinders, rectangles & aerofoils. In order to study the effect of sinks & sources in the flow of fluid, 8 openings are provided in the base plate. Each opening is connected to separate valves & thus can act as sink or source.
