Associate Professor Mechanical Engineering
Rajarshi Shahu College of Engineering, Tathawade, Pune
I've completed his bachelors and masters from University of Pune. Subsequently I earned his Ph.D. in the field of thermal hydraulics for nuclear reactor safety from Indian Institute of Technology Bombay. I've undertaken projects for characterization of critical heat flux in rod bundle and stability boundaries in multichannel natural circulation systems. I havebeen also provided consultancy to Larson & Tubro on severe accident analyses of Indian PHWR. My research area is mainly in experimental heat transfer in single phase and two phase flows. I've been in active academics from past 13 years. Currently working as associate professor in mechanical engineering at JSPM's Rajrshi Shahu College of Engineering, Pune (India) since Sept. 2023.

Abstract Several passive techniques can substantially improve the heat transfer performance of conventional heat exchangers. Passive methods persistently use heat transfer augmentation inside tubular sections, which tackle dominant thermal resistance. The thermal resistance in turbulent flow is primarily due to a thin viscous sublayer near the tube wall. This proliferates into the cross-section of the conduit in the case of laminar flows due to the existence of a relatively thicker boundary layer. This urges disturbance in the entire fluid throughout the cross-section in laminar flows, whereas augmentation devices are usually located close to the wall for turbulent flows. Most of these methods yield increased fluid residence time within the system by inducing swirling motion. The form of disturbance in the flow field is the characteristic of the passive technique used to prolong the fluid residence time and is exhibited differently in both flow regimes. The present article showcases a comprehensive review of heat transfer enhancement through thermo hydraulic performance assessment of these methods reported in the literature. The comparison is based on ratios of Nusselt numbers, first at the same Reynolds numbers, and then, at equal pumping power with constant heat transfer area.

The present investigations put forth the development of a novel double wall vented rotary fluid heating device. In this device, water is used as a process fluid and is heated by the combustion of sugarcane bagasse. The proposed combustion method is found to provide the use of a more systematic fuel transport system and ensure the efficient heat transfer process to the fluid. It is observed to offer many advantages over the conventional furnaces and obviates the use of any mechanized system such as traveling grate, fluidized bed system, dumping grate, etc. in conventional systems. Also, the heat liberated in combustion is used effectively for heating fluid through a helical coiled tube mounted over the surface of the drum. The present study aims to assess the thermal performance of the proposed rotary combustion chamber at different experimental parameters. It was concluded to have a maximum temperature rise, and the thermal efficiency of this system at 45.3C and 45.2% when drum speed is 6 RPM at Reynolds number equal to 1176.
