Evaporation and coalescence dynamics of impinging droplets and thin films on nanostructured surfaces of varying wettability

The project is focused on the investigation of the evaporation dynamics of a single impinging droplet and multiple interacting droplets as well as thin films over surfaces of varying wettability. The droplet also exhibits variations in heat transfer as well as evaporation rates in the radial direction depending on the surface wettability. In addition to the surface wettability, the droplet exhibits different evaporation regimes based on the temperature of the surface. Thus, with all these parameters, it is paramount to delineate the fundamentals of contact line evaporation, its dependence on surface wettability and temperature, and further understand the relationship between the motion of TCL and heat flux for different surface characteristics.

The objective is to exploit the high evaporation rate in the vicinity of the TCL which in turn provides high heat and mass transfer rates by meticulously tailoring the surface morphology to suit the varying areas of application.

CFD Analysis of Ventilation of Hostel Common Room in IIT Bombay

In the wake of the recent pandemic, social gatherings and interactions have been severely hampered due to the risks of SARS-CoV-2 transmission, which has rendered a major part of day-to-day life stagnant. This has significantly affected academia, research work, and hostel life in institutes across the world. In an attempt to ameliorate the possible risks of transmission, this study provides an effective ventilation solution for the Hostel-14 Common Room of IIT Bombay. This study deals with the simulation and analysis of flow patterns, air changes per hour (ACH), and air residence time (ART) in a common room of Hostel 14 at IIT Bombay based on the room's different exhaust and ceiling fan configurations. This project included studying the airflow within the common room, evaluating ventilation parameters, and providing suggestions on simple ways to mitigate recirculation regions

Thermal Behavior and Influence of Slip-flow Phenomenon on Performance Characteristics of Helium Lubricated Gas Foil Journal Bearing for High-Speed Cryogenic Turboexpander

Master’s degree research project, supervised by Prof. S.K. Behera. Developed in-depth knowledge of literature searching, problem-solving, programming along with modeling and simulations. .” A model is put forth to predict the pressure and film thickness of a Gas Foil Journal Bearing (GFJB) used in a helium-liquefaction turboexpander. The model addresses the slip at the gas-foil interface. Various performance parameters are assessed for the no-slip and slip-flow phenomenon in GFJB. The results are compared and a considerable difference is seen between the two models. This work was published in a journal and was also presented at an academic international conference through posters and oral presentations.

Thermal and Structural Analysis of Interference Fit of Lower Spindle and Coupling Seat using ANSYS

At the National Institute of Technology, Rourkela (NITR), I worked on a project “Interference Fit of Lower Spindle and Coupling Seat,” assigned by the Steel Authority of India (SAIL). The project involved the modeling of the hub and shaft and making an interference fit by heating the hub. I worked on the thermal and structural analysis of the assembly, which was carried out in ANSYS to study the stresses developed in the assembly. Heating and cooling characteristics for the process were also analyzed and a gas burner was designed for the required heating procedure.

Remaining Useful Life Estimation of Ball Mill using Statistical Data-Driven Approach

Undergraduate project under the guidance of Prof. Sarabjit Singh. Gained experience in maintenance data handling and insights into different types of failures encountered in the industry. It involved developing a model using condition monitoring data to estimate the remaining useful life of a ball mill used in the paint manufacturing industry. The model took account of various types of failures, viz electrical failure, bearing failure, and failure in the casing. Based on the data from three years, a model was put forth to predict the mean useful life and remaining useful life on a yearly basis.
