Geometry Optimization Of Building-Integrated Photovoltaic Sunshade, Seyedsoroush Sadatifar
Electronic Thesis and Dissertation Repository
Building-integrated photovoltaic (BIPV) systems are one of the growing applications of PV technology. These approaches allow PV panels to perform additional functions for the building, such as regulating interior lighting and incoming heat. In this work, we explore a design framework for optimizing the configuration of BIPV shading devices to optimize a combination of power generation, daylighting conditions within the building, and heating and cooling loads.
We develop a generalizable computational model and apply it to a case study for the Cornerstone Architecture Building in London, Ontario. We optimize the configuration of static and dynamic BIPV shading devices in both …
Analytical And Computational Modelling Of The Ranque-Hilsch Vortex Tube, Nolan J. Dyck
Analytical And Computational Modelling Of The Ranque-Hilsch Vortex Tube, Nolan J. Dyck
Electronic Thesis and Dissertation Repository
The Ranque-Hilsch vortex tube (RHVT) is a simple mechanical device with no moving parts capable of separating a supply of compressed fluid into hot and cold streams through a process called temperature separation. The overall aim is to develop models which can be used to assess the temperature separation mechanisms in the RHVT, leading to a better overall understanding of the underlying physics. The introductory chapter contains a thermodynamic analysis and introduction to the flow physics, alongside three miniature literature reviews and critiques identifying research gaps.
The body of the thesis contains three articles. The first article studies the flow …
Sustainable Smouldering For Waste-To-Energy: Scale, Heat Losses, And Energy Efficiency, Tarek L. Rashwan
Sustainable Smouldering For Waste-To-Energy: Scale, Heat Losses, And Energy Efficiency, Tarek L. Rashwan
Electronic Thesis and Dissertation Repository
Applied smouldering combustion is emerging as a highly energy efficient approach towards waste-to-energy. This thesis aims to better understand this potential by addressing a critical knowledge gap between laboratory scale smouldering research and large-scale applications. Altogether, new understanding in provided on the complex and dynamic interactions between the reaction zone (smouldering front) and the cooling zone (treated inert porous media) by integrating theory, experiments, analytical modelling, and global energy balance calculations. The experiments spanned a range of reactor sizes and smouldering conditions (from weak to robust) with dry (carbon) and wet (sludge) fuels mixed in sand. This work revealed that …

Development Of An Optical Guide For Parabolic Dish Solar Collectors, Zane Charran
Electronic Thesis and Dissertation Repository
With the possibility of a global energy crisis on the horizon, the need for renewable energy processes is more crucial than ever before. Solar energy, specifically solar concentrated collectors can provide a green alternative to fossil fuel consumption, but several factors need to be considered to improve their efficiency and make them viable. The present research is aimed at the development of a novel “Optical Guide” to improve performance of traditional thermal receivers in Parabolic Dish Solar Collectors for use in a domestic solar water heater with PCM latent heat storage integration. Two ray trace programs, SolTrace and Tracer were …
