Who says research isn’t cool!

If air conditioners and refrigerators become much more efficient in the days to come, you'll probably want to tip your hat to research scholar Atul Soti.

Atul works in the area of enhancing heat transfer in exchanges between solids and liquids.

The air conditioner cools the room by exchanging heat with the environment. Likewise, in power plants, water is converted into steam. Atul is hoping that his work will help increase the efficiency of these processes.

His research project, under the supervision of Prof Mark Thompson and Prof Rajneesh Bhardwaj, is titled, 'An Immersed-Boundary method based solver to compute flows with solid–fluid and fluid–fluid interfaces'.

Graduate research scholars of the IITB-Monash Research Academy like Atul study for a dually-badged Ph.D. from both IIT Bombay and Monash University, spending time at both institutions to enrich their research experience. The Academy is a unique collaboration between India and Australia that endeavors to strengthen scientific relationships between the two countries

Shedding light on his work, Atul says, "Computational Fluid Dynamics (CFD) is a fascinating area to work in. Flows with solid–fluid and fluid–fluid interfaces are relevant to multiphase problems such as the interaction of a droplet with a solid surface, flow segmentation in a microchannel, bubble dynamics in a channel, and bubbly flows. My aim is to develop a generalized flow solver with solid–fluid and fluid–fluid interfaces. The flow in many of the above applications is highly unsteady and the modeling of the structure also involves geometric and material nonlinearities. While modeling of the flow and the structure are challenging in their own right, the coupled fluid-structure interaction and the inclusion of the fluid-fluid interface raises the challenge to an even higher level. Although most commercial software have Fluid–Structure interaction (FSI) and two-phase capabilities, they are many times limited to smaller deformation and require more pre-processing time. We propose to build a fast versatile solver which can work with minimal user input."

"As the reputation of The IITB-Monash Research Academy begins to grow and as more organizations start collaborating with the Academy, we anticipate that it will contribute to maintaining India's reputation as a leading-edge global research hub," says Dr. Murali Sastry, CEO, IITB-Monash Research Academy.

"Multiphysics problems such as Fluid–Structure Interaction (FSI) are the next challenge to the scientific community and are more close to real world problems," adds Atul. "Numerical solutions to such highly non-linear problems is a very powerful tool from both the scientific and engineering points of view. My work involves understanding many advanced concepts like Parallel programming, Fast Poisson solvers, coupling schemes, level set methods, material non-linearity, etc. Someday I hope to develop the fastest CFD solver!"

No wonder Atul's friends think he's doing some really cool research

The work being undertaken by Raghavendra can have a significant impact on restricting the increase of global temperature to below 2°C, the figure agreed on during the recent climate change summit in Paris. We'll be watching his progress closely.
