WIND TUNNEL
This is an open circuit Wind Tunnel which provides a region of
controlled airflow into which models
can be inserted. The propulsion is provided by a fan at
downstream of working section.
The tunnel consists of bell mouth shaped entry to guide the air
smoothly into settling chamber
consisting of honeycomb and nylon mesh screens which filters and
stabilizes the air flow. This follows
working section or test section where various models can be
tested. Two windows with acrylic sheetone each on either side will
be provided for visual observation. Working section is followed by
diffuser
section, which reduces the dynamic pressure at the exit.
A three -blade fan coupled with .! variable speed motor is
used to produce desired wind velocity. A
thyristorised motor control is used for smooth variation of air
velocity.
