Aerodynamics

Aerodynamics is the study of forces and the resulting motion of objects through the air. Judging from the story of Daedalus and Icarus, humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years. Aerodynamics affects the motion of a large airliner, a model rocket, a beach ball thrown near the shore, or a kite flying high overhead. The curveball thrown by big league baseball pitchers gets its curve from aerodynamics.There are quite sophisticated instruments the lab competing with some of the worldclass facilities.These include:


Subsonic Wind Tunnel

 

The suction-type low speed subsonic tunnel has a test section size of 61cm X 61cm. The wind speed in the test section may be varied from 18m/sec to 35m/sec. Experiments related to measurement of surface pressure distribution as well as overall forces and moments on a variety of models are conducted in the tunnel, using 3-component electronic wind tunnel balance.

Airflow Bench

 

Airflow Bench is a compact low speed wind tunnel where air speed in the test section can be varied continuously upto 33m/sec. Using different test sections, severel experiments involving flow visualisation, measurement of pressure, forces and moments as well as boundry layer in favourable and adverse pressure gradiants are conducted on small models.


Supersonic Wind Tunnel

 

In this blow down tunnel, supersonic flow at Mach number 2.2 is achieved in the 5cm X 10cm test section. The tunnel is equipped with a Schliren system for shock observation.

Gust Tunnel

 

The gust tunnel has a test section size of 61cm X 91.5cm where wind speed can be varied continuously upto 34m/sec. Models under steady and oscillatory flow conditions can be used to measure various performance parameters.


Industrial Tunnel

 

The Industrial tunnel has a test section of size 2.25m X 1.5m. This is built for applications involving studies of atmospheric boundary layer, road vehicle aerodynamics, air pollution etc. The maximum speed in the test section is 16m/sec.
