Wind Tunnel Description and Specifications for Lab Tenders
Wind Tunnel.
Wind Tunnel
WIND TUNNEL” has been developed to perform various experiments of
aerodynamics and fluid flow. This is a open circuit Wind Tunnel provides
a region of controlled air flow into which models can be fitted at
downstream of working section. The Tunnel consists of bell mouth shaped
entry to guide the air smoothly into settling chamber and stabilizes the
air flow this follows working section for test section where various
models can be tested. Test section with acrylic sheet, will be provided
for visual observation. Working section is followed by diffuser section
which reduces the dynamic pressure at the exit. A fan coupled with motor
is used to produce desired wind velocity.
Experimentation:
To plot speed curve for wind tunnel.
T study pressure distribution around (A) aerofoil (B) Cylinder (C) Sphere.
To measure lift and drag on aerofoil model.
To study the development of boundary layer along a plate in Tunnel.
