Additively-manufactured Deterministic Porous Structures for Transpiration Cooling
(University of Waterloo, 2023-07-17)Transpiration cooling is increasingly being studied as a method of thermal protection in hypersonic flight, rocket engine liners, and gas turbines. To date, materials for transpiration cooling have been restricted to porous ... -
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 ... -
Design and Optimization of Low-Specific Speed Centrifugal Pump
(University of Waterloo, 2023-04-21)Centrifugal pumps find applications in a wide range of industries, such as rocketry, oil and gas, petroleum, etc. A main property used to characterize the design of pumps is the specific speed, which relates the flow ... -
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 ... -
Imaging of Thermal Propagation in Combustion of Al/CuO Core-Shell Nanothermite Film
