Numerical Simulation and Experimental Study of Transient Liquid Phase Bonding of Single Crystal Superalloys
(2011-10-07)The primary goals of the research in this dissertation are to perform a systematic study to identify and understand the fundamental cause of prolonged processing time during transient liquid phase bonding of difficult-to-bond ... -
Numerical simulation of 2D flow past a dimpled cylinder using a pseudospectral method
(2007-01-08)A numerical simulation of steady and unsteady two-dimensional flows past cylinder with dimples based on highly accurate pseudospectral method is the subject of the present thesis. The vorticity-streamfunction formulation ... -
Numerical simulation of the crack propagation in a pipeline subjected to third-party damage
(2015)With over 830,000 km of operating pipeline in Canada alone, their safe and continued functioning underpins much of daily life. A key type of risk associated with pipelines is third-party damage, damage caused by actions ... -
Numerical simulation of transient liquid phase bonding under temperature gradient
(2013-07-30)Transient Liquid Phase bonding under Temperature Gradient (TG-TLP bonding) is a relatively new process of TLP diffusion bonding family for joining difficult-to-weld aerospace materials. Earlier studies have suggested that ... -
Numerical simulation of transient liquid phase bonding with variable diffusion coefficient in planar, cylindrical and spherical systems
(2019-01-16)A new finite difference numerical model with variable diffusion coefficient is developed by using an explicit-fully-implicit hybrid method and Landau transformation with adaptable spatial discretization to study TLP bonding ... -
Numerical solution of a two-phase model for laminar film condensation of vapour-gas mixtures in channels
(2001-05-01)The present analysis deals with steady-state, internal-flow, laminar film condensation of vapour-gas mixtures in horizontal and downward-inclined parallel-plate channels. The cooled lower plate is maintained at a uniform ... -
Numerical stability and heat transfer analyses of supercritical water flowing upward In vertical heated pipes
(2014-03-27)A numerical study is performed to model the 2-D axisymmetric turbulent flow of supercritical water flowing upward in vertical pipes with constant wall heat fluxes, using ANSYS CFX v14.5. This study was aimed to use CFD in ... -
A numerical study of a highway embankment on degrading permafrost
(2015)In this research, two comprehensive numerical models were developed using ABAQUS/CAE Finite Element (FE) software: 1) geothermal model, and 2) coupled thermo-hydro-mechanical model. In the first model, a purely heat transfer ... -
Numerical study of biomass combustion of a grate-firing furnace with emphasis on gas-phase combustion modeling
(2018)As a renewable energy resource, biomass is slowly becoming a substitute for traditional fossil fuels due to global warming concerns and limited availability of fossil fuel resources. Direct combustion of biomass in ... -
A numerical study of penalized regression
(2013-08-22)In this thesis, we review important aspects and issues of multiple linear regression, in particular on the problem of multi-collinearity. The focus is on a numerical study of different methods of penalized regression, ... -
Numerical study of projectile shape effect on the bumper performance under hypervelocity impact
(2023-03-29)Impacts in orbit from small micrometeoroids and small non-trackable orbital debris are generally unavoidable and pose a threat to spacecraft due to the high collision speeds exceeding 7 km/s. The design of spacecraft ... -
A numerical study of the axial compressive behavior of a hyperelastic annular seal constrained in a pipe
(2016)Elastomer seals are used in a variety of industries that require flow isolation. The characterization of the behavior of these seals remains largely unexplored and hence, this study is focused on simulating and validating ... -
Numerical tests of approximations used in theories for cosmic ray transport
(2018)One of the challenges in astrophysics is describing the motion of cosmic rays in chaotic magnetic fields. I present a qualitative analysis of results from simulations of the motion of cosmic rays in axisymmetric turbulent ... -
Nurse educators' perceptions of ecoliteracy in undergraduate nursing programs
(2017)Knowledge about the relationship between human health and the environment is continuously expanding. Nurses are well positioned to address environmental and ecological health concerns related to human health. Yet, there ...
