How important are differential and preferential diffusion effects for hydrogen combustion?

Auditorium (AE 005), Department of Aerospace Engineering

Hydrogen is coming to the forefront as a potential energy carrier to achieve decarbonisation goals and objectives. It is well known that hydrogen is a light molecule diffusing quicker than other molecules and thermal energy in the fuel-air mixture of hydrogen combustion systems. Critical evaluations of these effects have been studied for many decades, suggesting […]

M.Tech (Res): Direct Numerical Simulation of Turbulent Aerosol Transport in Human Respiratory Flows

AE Conference Room , AE 003

Airborne transmission of respiratory diseases is governed by the coupled dynamics of the exhaled turbulent flow and the transport of pathogen-laden aerosols and droplets. This thesis studies two representative respiratory activities, speech and cough, and quantifies the infection probability using Direct Numerical Simulations. The incompressible Boussinesq Navier-Stokes equations are solved using Megha-5 solver, including the […]

Ph.D. (Engg): Splashing of impacting drops on rigid and flexible superhydrophobic surfaces

STC Seminar Hall, Dept. of Aerospace Engineering

Understanding droplet impact dynamics on superhydrophobic (SHP) surfaces is crucial for exploiting their exceptional liquid-repellent properties in various industrial applications. Studies on high-velocity droplet impacts on SHP surfaces, particularly under splashing conditions, are of significant importance for applications such as anti-icing and erosion protection of turbine blades. This thesis presents an experimental investigation of splashing […]
