This thesis reports the study of flow inside a honeycomb type substrate. Honeycomb monoliths are extensively used in the automotive industry, as substrates in the exhaust gas after-treatment system. The flow approaching a honeycomb monolith is usually highly turbulent; However, once entering the...

The overall objective is to research methods for the efficient simulation of structured reactors using models that can capture as much of the real micro scale phenomena as possible within the constraint of running in a realistic amount of computer time. The problem of modelling a complete...

Turbulence is a chaotic motion of fluid that can be described by the Navier--Stokes equations or even highly simplified shell models. Under the continuum limit, standard shell models of turbulence are shown to reduce to a common evolution equation that reproduces many predictions of the...

This work presents the numerical study of chemically reacting char particles in dense particulate media applied to fixed and fluidized beds. Our main goal was to approximate 3D fixed bed particles into 2D axisymmetric geometry using a representative element, which is found in Chapter 1. Dry air...

This work focuses on validation of a commercial computational fluid dynamics (CFD) software ANSYS Fluent 16.2 applied to multi-phase modeling of fluidized beds. A two-phase Eulerian-Eulerian based model is used to numerically reproduce experiments carried out by Taghipour, F. et al (Chem. Eng....

Fluidized beds offer efficient solutions for segregation of clay and bitumen pellets in the oil production industry. However, the hydrodynamics of these systems is not well-known and they are mostly operated as ``black box''. The removal of clay pellets in the mechanical separation of oil sands...

In modern cosmology, many efforts have been put to detect primordial B-mode of cosmic microwave background polarization from the gravitational waves generated during inflation. Considering the foreground dust contamination of microwave polarization maps, it is essential to obtain a precise...

It has been well known that turbulent motions are ubiquitous in the interstellar medium. These motions are very important in governing various astrophysical processes like star formation. Both observational and numerical studies are important to understand turbulent motions, and a gap between...
