As the particle size goes down, it starts agglomerating/clustering. Problem of agglomeration amongst the nanoparticles hinders its performance in many of the potential application. One of such application is its fluidisation. Generally, it has been reported that the formation and breakage of nanoparticle agglomerates decide the behaviour of fluidisation. For the breakage of particles usually external source of vibration is required. To our interest is the energy supplid through vibration. We are interested in finding out how and what role vibration plays in the breakage and formation of agglomerates. We are performing DEM simulation at different configuration to explore the same. For the readers reference, I kept gif of the simulation of agglomeration and deagglomeration process of nanoparticles in a periodic box.

CFD-DEM simulation is widely used to support and explain the expiremental findings in the area of fluidisation of particles. Here, I am simulating the bed of binary particles of different size and density. Simulation will help in explaining result reported by experimentalist of our group. I am keeping a gif of fluidisation of binary particles.

We used CFD tool to simulate gas flow in different ALD reactors. ALD is sensitive to the gas flow and temperature of the reactor. CFD simulation of such reactors will be useful in optimisation of the ALD process.

For a better understanding of the evolution of COVID-19 in the world, study on evolution and growth of cases in India could not be avoided. To understand the same, one of the compartment model: Susceptible-Infectious-Quarantined-Recovered (SIQR) is used. I did this analysis in my spare time during COVID lockdown.
