Project Report from the year 2016 in the subject Engineering - Civil Engineering, grade: AA, Priyadarshini College of Engineering, Nagpur, course: B.E AERONAUTICAL ENGINEERING, language: English, abstract: This text depicts how a low speed water tunnel was designed and fabricated, as well as tested and analysed. The low speed recirculating type water tunnel was successfully designed and fabricated. The designing was done by taking into consideration of the Reynolds no. flow velocity, boundary layer formation, cavitation number and Froude¿s number. Theoretical and computational studies were made to decide the shape and the size of the various components of the low speed water tunnel. Uniformity in the setup of main objective and was successfully achieved. The setup consists of an inlet plenum with baffle to reduce turbulence or splashing, honeycomb structure, converging section, test section and wide angle diffuser and outlet module suitable low power single phase motor was selected for continuous flow of water in the setup. The water was recirculated using this motor and appropriate plumbing system. All the components were designed, analyzed, constructed and installed successfully .General purpose polymer was used as a ground material for the fabrication purpose. Necessary up gradations were made during various stages of the project. Flow visualization over the test bodies was successfully visualized using a dye injection system.
