Exploring the Field of Nanofluids
Jan 08, 2018 | Sahithi Ravipati
It is of great pride when alumni come back to interact with the present student community. Recently, Prof. Debendra K. Das from the University of Alaska Fairbanks School of Engineering, a graduate from the Department of Mechanical Engineering of the 1972 batch, he was a Gold Medal recipient and graduated with the highest percentage among all branches of the then REC. He then pursued his M.S. in Mechanical Engineering from Brown University in 1974 and PhD in Mechanical Engineering from the University of Rhode Island in 1983. He pursued his PhD under the renowned Prof. Frank M. White.
On January 6th, 2018, a seminar on the topic An Experimental Study Using Nanofluids in Hydronic Heating Coils in Buildings was held at the Pranakrushna Parija Auditorium at 11:00 AM and went on until 12:30 PM. The seminar was attended by about 50 students, Prof. D.K. Parhi, Prof. S.K. Patel, Prof. Murugan and Prof. Moharana.
In this seminar, Prof. D.K. Das explained to the students about the different types of heating systems and the latest nanofluid developments in this system. He gave a basic introduction to the likes of Ferrofluids and Nanofluids and how they are used in heating systems. He explained that traditionally, water is used in heating systems in warm places where as Ethylene Glycol is used in colder places such as Alaska. He told the students that as Nanofluids is a new concept, there are many factors such as Density, Viscosity and Specific Heat that need to be explored. In association with his students like Vajjah and Sahoo, he worked to find information and equations regarding these matters. He spoke of comparisons of Heat Transfer in different Nano Fluids like 1% Al2O3 and 60% Ethylene Glycol. He concluded his presentation by explaining the Thermal Processing of Tomato Juice. He explained the Nano Particles are effective to reduce the size of Heat integrators which will be of great benefit.
The seminar finally concluded with Prof. D.K Das opening the floor for questions. He guided students about pursuing a PhD in the US and other matter. He advised them to never lose hope.
