Aeroacoustics of Compressible Vortex Reconnection
(University of Waterloo, 2021-08-27)Aeroacoustics is a key focus in the design of propulsion, energy, and transportation systems. Noise generation in these systems is caused by the unsteadiness of the flow and simplified acoustic models are used to approximate ... -
Capillary-discharge ignition of dispersed-phase Al@CuO core-shell thermite particles in a liquid filled microchannel
(University of Waterloo, 2022-11-09)Aluminum based thermites are a broad class of highly tunable solid energetic materials that can be formulated to perform as pyrotechnics, propellants, or explosives. Their functional versatility, energy density, reactivity ... -
Continuum Modelling of Al/CuO Nanothermite Pellet Combustion
(University of Waterloo, 2020-06-15)Nanothermite mixtures are made up of nano-sized metallic fuel and inorganic oxidizer components. As this solid mixture represents a metastable intermolecular composite, an increase in nanothermite temperature can initiate ... -
Experimental analysis of coherent structures in a plane confined jet
(University of Waterloo, 2019-09-26)Confined jets are commonly employed in several industrial applications such as propul-sion systems in the aerospace industry and environmental control systems. In the presentstudy, the flow development of a high ... -
Integration of Transpiration Cooling and Shock Thrust Vectoring
(University of Waterloo, 2022-06-16)Transpiration cooling is used for active thermal protection whereas shock thrust vectoring is an attitude control approach. Both concepts rely on the injection, at the wall, of a secondary fluid into a high-speed and ... -
Modelling Aerothermal Heating with Conjugate Heat Transfer
(University of Waterloo, 2022-01-27)Supersonic and hypersonic vehicles experience flows under complex thermodynamic conditions due to the presence of shock waves and large thermophysical gradients. A large thermal load is imparted to the vehicle from the ... -
Numerical Analysis of Transpiration Cooling on a Turbulent Flat Plate
(University of Waterloo, 2020-01-14)Transpiration cooling is a promising thermal protection system for gas turbines, atmospheric re-entry heat shields, and rocket engine combustion chambers. Design of transpiration cooling systems must rely on numerical ... -
Prediction of Forces and Moments in Multiphase Naval Simulations
(University of Waterloo, 2020-01-23)This thesis investigates the prediction of forces and moments in the static and dynamic planar motion mechanism (PMM) simulations of ship manoeuvring problems using the open-source Computational Fluid Dynamics (CFD) software ... -
Riemann solvers with non-ideal thermodynamics: exact, approximate, and machine learning solutions
(University of Waterloo, 2022-09-22)The Riemann problem is an important topic in the numerical simulation of compressible flows, aiding the design and verification of numerical codes. A limitation of many of the existing studies is the perfect gas assumption. ... -
Stability of compressible boundary layers in presence of smooth roughness and wall temperature effects
(University of Waterloo, 2023-01-26)In natural laminar flow design, aircraft manufacturers aim to delay the laminar-to-turbulent transition by modifying the geometric features of the aircraft to stabilize the boundary layer. Yet, the transitional process is ... -
Thermal Comfort Analysis Inside of a Recreational Vehicle
(University of Waterloo, 2020-01-27)The focus of the current study is on the numerical investigation of airflow and temperature distribution in a representative Class B Recreational Vehicle (RV) with the objective of optimizing the inlet and exhaust vent ... -
Thermoacoustic Instabilities in Counterflow Diffusion Flames
(University of Waterloo, 2019-09-23)Thermoacoustic instabilities arise in combustion systems from a coupling between the unsteady heat release of the flame and the underlying acoustic field. Although thermoacoustics have been studied extensively with regards ... -
Velocity scaling of high-speed turbulent boundary layer flows with wall heat transfer
(University of Waterloo, 2021-07-19)The law of the wall has been a staple in collapsing the mean velocity profiles of seemingly very different turbulent channel and boundary layer flows into one single, semi-analytical function. Accordingly, it has equipped ...
