Research & Project Interests

Dr. Subramanian's main interest is in structure of turbulence in various types of complex flows (including vortex imbedded boundary layers; curved shear layers; rigid, large, and flexible roughness effects; rotating shear layers and unsteady flows). The purpose is to explain the underlying mechanism of turbulence and to develop better flow models, which will help to develop more efficient engines for space vehicles and high-performance airfoils for the future generation airplanes. Other interests include:

  • Design, testing and development of flow measuring instruments, such as wireless sensor network, laser Doppler, particle imaging and hot-wire anemometers; miniature pressure and temperature probes; and pressure-sensitive and temperature-sensitive paints. Flow visualization using laser induced fluorescence.

    Wind loading on structures and road vehicles. Hazard mitigation

  • Detection of debonding in Thermal Protection System of Shuttle Orbiter and Detection of Lightning through Clouds Using Short-Pulse Lasers and Streak Camera.

  • Gas turbine film-cooling, internal combustion and hydraulic propulsion systems. Alternative fuels. Desiccant air-conditioning systems

  • Wind tunnel design and aerodynamic testing.
