Research activities:

Combustion studies with primary target of reducing pollutant emissions and increasing fuel utilization efficiency. A multidisciplinary subject, combustion needs understanding of fluid mechanics (including turbulence and acoustics), heat and mass transfer, thermodynamics, chemical kinetics, multiphase phenomena etc. From a learners’ perspective such studies are quite involved and stimulating due to variety of topics as well as of experimental, numerical and analytical techniques. Practically, these studies are needed to solve issues with low air pollution and reduce overall fuel usage. This is important in present times with increasing growth in energy consumption, threats of global warming and environmental deterioration. Combustion finds its applications in power, transport, aerospace, manufacturing, and various process industries. Furthermore, it is commonly encountered in many domestic uses, buildings (space heating and cooling), agriculture and rural applications. A specific challenge, relevant for India, is to utilize locally derived fuels in local applications.

Currently, students are working on fundamental as well as conceptual design level studies in combustion predominantly using simulation techniques. Software as OpenFOAM, COMSOL, ANSYS-FLUENT, CONVERGE, CANTERA are being utilized for these purposes. Design and fabrication of an experimental combustion test rig is also in progress, which would allow experiments in turbulent flames in near future. Some simple experiments can be rigged in various laboratories of the Mechanical Engineering dept. Focus of industrial combustion studies is on turbulent lean premixed combustion and low temperature combustion strategies for reducing various air pollutants such as NOx and particulate matter. However, they require solving challenges with carbon-monoxide and unburned hydrocarbons emissions and combustion dynamics. Another focus area is on combustion studies relevant to rural applications and small and medium scale Indian industries.
