Fall 2013
In the development of a numerical model for the water cycle on Mars, adsorption of water vapour in the Martian regolith acts as a significant sink and retards the transport of mass. Adsorption on Mars cannot be studied directly, so a numerical model was created, and a diffusion sorption...

Characterization and Control of Cyclic Variability in a Gasoline/Natural Gas Dual-Injection Spark Ignition Engine
DownloadSpring 2016
Reducing the cyclic variability of a gasoline/natural gas dual injection spark ignition engine using minimum variance control is the subject of this thesis. Cylinder pressure is used to calculate four combustion metrics, the standard deviation of which is used as an indicator of cyclic...

Fall 2012
To understand the water cycle on Mars, details of mass and energy transfer between the surface and the atmosphere are of importance. A complete model, involving transient variations of the water in gaseous and solid phases in the atmosphere and the regolith, is developed and solved numerically...

Effects of Negative Valve Overlap on HCCI Combustion and its use in the Control of HCCI Combustion Timing
DownloadFall 2014
Homogeneous charge compression ignition (HCCI) combustion can produce higher efficiencies and lower emissions when compared to tradition spark or compression ignition engines. This study reports an experimental investigation into the effects of valve timings on HCCI combustion conditions. Using a...

With continued growth in global carbon emissions, much of the developed world is curtailing its dependence on fossil fuels. Broad decarbonization will not come from a single source, but rather a combination of policy, technology, and innovation. Wind power has seen significant development in...

A dual-fuel system is used to control HCCI combustion timing and load in a CFR engine. The systems steady-state response to iso-octane and n-heptane injected energy is investigated then a dynamic ARMAX model is found using system identification. This model is used to design a norm-optimal...

Techno-economic feasibility of hybrid energy systems for small-scale space heating applications in Canada
DownloadSpring 2021
Given the large energy consumption for space heating demands in Canada, renewable energy heating systems are becoming increasingly more popular and more important for small scale applications. However, these face tough challenges for applicability in cold climate regions due to various physical...
