WIND TUNNEL TEST RIG (VARIABLE SPEED WITH AC MOTOR)

PRODUCT DETAILS

Description

"WIND TUNNEL" has been developed to perform variousexperiments of aerodynamics and fluid flow. This is aopen circuit Wind Tunnel provides a region of controlledair flow into which models can be fitted at downstream ofworking section. The Tunnel consists of bell mouthshaped entry to guide the air smoothly into settlingchamber and stabilizes the air flow. This stabilized airfollows working section or test section where variousmodels can be tested. Test section with acrylic sheet, isprovided for visual observation. After working section airleaves the diffuser section which reduces the dynamicpressure at the exit. An axial fan, coupled with motor isused to produce desired wind velocity in the tunnel. Aspeed control unit facilitates user, to haveexperimentations on different speeds, to enhance thestudy. RPM of the fan are measured and indicated on adigital RPM indicator in control panel.The air flows through a test section whereinstrumentation has been done to measure the pressurehead, velocity and flow. A pitot tube with differentialpressure manometer is provided to observe and find outthe static and dynamic head of air, flowing through thewind tunnel. The test section is also fitted with X, Y forcemeasuring arrangement. When different types of modelsare installed in the test section for the study andexperimentations, a digital read out indicates the forceson models. To measure pressure head distributionaround the models, under study, an inclinablemanometer bank is also provided.
