Research

- Shock waves and instabilities in granular flows.
An experimental campaign is launched at the Aerospace Engineering department to investigate shock waves and instabilities in granular flows under the guidance of Prof. Sanjay Kumar and Prof. Rakesh Kumar. The project is funded by the Department of Science and Engineering Board, India.
- Swept shock wave/turbulent boundary layer interaction.
An experimental investigation is carried out to control the steady and unsteady characteristics of the threedimensional swept shock wave and turbulent boundary layer interaction using micro-vortex generators for applications in supersonic inlets. Research work is conducted in collaboration with National Aerospace Laboratories (NAL), Bangalore, India.
- Experimental and numerical investigation of plug nozzle flows.
The project involves the development of plug nozzles for application to launch vehicles. The project is supervised by Dr. Rakesh Kumar and is funded by the Indian Space Research Organization (ISRO),India.
- Aerodynamic and aeroacoustic investigation of multiple jets.
The project involves the investigation and control of the mixing characteristics of supersonic jets from converging-diverging nozzles operating under chocked conditions. Vortex generators are used to enhance the mixing characteristics and reduce the screech and shock-associated noise from closely spaced twin jets. The project is supervised by Dr. Rakesh Kumar.
- Supersonic jet control using fluidic injection.
The aerodynamic and aeroacoustic characteristics of a supersonic jet exiting from a converging-diverging nozzle are manipulated by injecting secondary jets from mini injectors that are oriented normal to the primary jet. The project is supervised by Dr. Rakesh Kumar and Dr. Arun Kumar Perumal
