Computational fluid dynamic investigations of flow through an aged CANDU pressure tube
(2021-08-01)
Single-phase, isothermal computational fluid dynamics simulations of twelve simplified CANDUTM 37M fuel bundles sitting in both as-received and aged pressure tubes were performed with Hydra in this work. The predicted ...
A CFD analysis of the pressure drop through misaligned Stirling engine regenerators
(2021-04-01)
Experiments were conducted to discover the average misalignment in wire mesh regenerators, and it was found that regardless of the intended stacking arrangement, the average misalignment was 44% to 49%. A 3-dimensional CFD ...
Design and analysis of an active underbody aerodynamic device for tractor trailers
(2018-04-01)
At highway speeds, up to 65 % of the total energy used by large trucks is for overcoming aerodynamic drag. The underbody region of a tractor-trailer is responsible for up to 30 % of the aerodynamic drag on tractor-trailers, ...
Assessment of FLUENT CFD code as an analysis tool for SCW applications
(2012-08-01)
Chosen as one of six Generation‒IV nuclear-reactor concepts, SuperCritical Water-cooled Reactors (SCWRs) are expected to have high thermal efficiencies within the range of 45 ‒ 50% owing to the reactor‟s high pressures and ...
A Computational Fluid Dynamics based model that predicts wall shear stress in CANDU outlet feeder pipes
(2018-01-01)
Wall thinning of carbon steel in CANDU reactor outlet feeder pipes due to Flow Accelerated Corrosion (FAC) is identified as one of the challenges for CANDU reactors since it would force them to shut down due to safety ...
Thermal characterization and modeling of an energy storage system
(2020-09-01)
The thesis reports a virtual design tool that was developed to predict and analyze thermal loads in an electric vehicle charging system. The tool was designed using computational fluid dynamics techniques and validated ...
CFD determination of fluid and geometry related localized heat transfer phenomena for supercritical water flow
(2017-04-01)
The proposed concept of Supercritical Water-cooled Reactor (SCWR) as part of the Generation IV International Forum aims to improve the thermal efficiency over current power plants by utilizing cooling water at pressures ...
Development of a method for genetic optimization of aerodynamic devices
(2021-06-01)
Driving stability, fuel efficiency and soiling reduction are important for modern vehicles. This thesis has developed a novel method for genetic optimization of aerodynamic devices for road vehicle applications with the ...
Modelling of radioactive particle resuspension after a dirty bomb event
(2023-12-01)
The primary hazard of a Dirty Bomb emanates not from the initial detonation but from the subsequent re-suspension of deposited radioactive particles. Although radiological contamination is substantial on surfaces initially, ...
