The Boltzmann collision kernel and the widely used Bhatnagar–Gross–Krook (BGK) model are limited to monatomic gases as they do not account for the internal molecular structure. However, many real gases such as nitrogen, ...

Lanczos algorithm is an effective tool for constructing an approximate tridiagonalization of a symmetric matrix. The basic procedure creates a set of vectors and makes them orthogonal to create an orthonormal basis of ...

The second wave of COVID-19 led to a severe scarcity of medical oxygen in the country, as cryogenic distillation plants could not entirely meet the exigent oxygen requirements for medical usage. Consequently, there has ...

This thesis broadly deals with inertial effects on the motion of passive anisotropic particles and can be divided into four parts. Orientation dynamics of spheroids settling in turbulence The first part of the thesis ...

We present a particle-continuum coupling for simulations in the laminar and turbulent flow regimes. The two-way coupling in the hybrid model is achieved via a direct Simulation Monte Carlo layer near walls and a ...

Coronary artery disease (CAD) is a widespread cardiovascular illness that causes high rates of mortality all around the world (World Health Organization 2016; Kaptoge et al. 2019). The diagnosis of coronary artery disease ...

A number of scientific and engineering systems are governed by PDEs which have solutions comprising wide range of spatial and temporal scales. The accompanying details can only be captured by high-fidelity simulations on ...

This thesis is focused on the effect of polymer solutions on two caricature flows, namely the instability in a pipe with reverse flow and vortex rings. These caricature flows are intended to be representative of the wall ...
