The focus of our research group is to study transitional and turbulent flows in a variety of different contexts. We are motivated by the quest to understand the rich and fascinating complexity exhibited by these flows by investigating their scaling and structure. The problems we tackle include turbulent boundary layers, turbulent jets, transitional boundary layers, channel flows etc. A recurring theme in our work is to perturb a flow to study its response and to understand its behaviour by measuring its departure from the canonical state. Towards this we use experimental, computational and theoretical tools as may be fit for a given problem. We constantly seek to translate our laboratory research into applications of relevance to industry and society. Some examples include the delay of transition to reduce drag and enable greener transport, reduction of the severity of hot spots towards enhancing the lifetime of gas-turbine blades and quantifying the transport of aerosols during cough and speech relevant to the spread of COVID-19-type diseases. Another important theme of our work is applied aerodynamics. We house the largest wind tunnel in India and offer wind tunnel consultancy and R&D support to major aerospace and automobile development programs in India. We are a vibrant group of people committed to academic excellence and scholarship.
