The main activity of the research group is in the area of supersonic aerodynamics. An open-jet supersonic wind tunnel facility is being established as in-house project entitled “Installation of open-jet supersonic wind-tunnel with Data Acquisition System”. The tentative date of completion of facility/project is March, 2013. The project will be completed in two phases. In the first phase, hardware part i.e. supersonic wind tunnel will be installed whereas data acquisition system will be incorporated in the second phase. The flow field over various aerodynamic bodies in the supersonic regime will be investigated and analyzed.
