Dynamics of Acoustically Levitated Ice Impacts on Smooth and Textured Surfaces: Effects of Surface Roughness, Elasticity, and Structure
Adam McElligott, André Guerra, Alexandre Brailovski +6
Through acoustically levitated ice formation and subsequent release onto a controlled area, this study introduces a third class of ice-countering system beyond de- and anti-icing:…
Non-Einsteinian Viscosity Reduction in Boron Nitride Nanotube Nanofluids
André Guerra, Adam McElligott, Chong Yang Du +3
(1) Introduction: Nanoparticles have multiple applications, including drug delivery systems, biosensing, and carbon capture. Non-Einstein-like viscosity reduction has been reported…
Dynamic Viscosity of Methane Hydrate Systems from Non-Einsteinian, Plasma-Functionalized Carbon Nanotube Nanofluids
Adam McElligott, André Guerra, Chong Yang Du +3
The viscosity of oxygen-functionalized multi-walled carbon nanotube (O-MWCNT) nanofluids was measured for concentrations from 0.1 to 10 ppm under conditions of 0 to 30 MPag pressur…
Effects of Poly(styrene/pentafluorostyrene-block-vinylpyrrolidone) Amphiphilic Kinetic Hydrate Inhibitors on the Dynamic Viscosity of Methane Hydrate Systems at High-Pressure Driving Forces
Chong Yang Du, André Guerra, Adam McElligott +2
Reversible addition-fragmentation chain-transfer polymerization with a switchable chain-transfer agent was employed to synthesize amphiphilic block copolymers poly(styrene-b-vinylp…
Non-Einsteinian Viscosity Behavior in Plasma-Functionalized Graphene Nanoflake Nanofluids and their Effect on the Dynamic Viscosity of Methane Hydrate Systems
Adam McElligott, André Guerra, Chong Yang Du +3
Water's viscosity dependence on pressure was also not affected by O-GNFs, except at 10 ppm, where the shuttle effect may have increased the presence of hydrophobic methane bubbles…
Interfacial Effects during Phase Change in Multiple Levitated Tetrahydrofuran Hydrate Droplets
Adam McElligott, André Guerra, Alexia Denoncourt +2
In this study, using direct digital and infrared imaging techniques, the freezing of up to three simultaneous THF hydrate droplets was investigated for the first time. Nucleation w…
Effects of Poly(vinylpyrrolidone) on the Dynamic Viscosity of Methane Hydrate Systems at High-Pressure Driving Forces: Investigation of Concentration, Molecular Weight, and Shear Rate
Chong Yang Du, André Guerra, Adam McElligott +3
The viscosity of methane hydrate slurries with poly(vinylpyrrolidone) (PVP) at 700 and 7000 ppm by weight, molecular weights of 40,000 (PVP40) and 360,000 (PVP360) Da, and shear ra…
TinyLev Acoustically Levitated Water: Direct Observation of Collective, Inter-Droplet Effects through Morphological and Thermal Analysis of Multiple Droplets
Adam McElligott, André Guerra, Michael J. Wood +3
Initially, the acoustic field forced the droplets into an oblate spheroid shape, though the counteracting force of the cooling stream caused them to circularize. Droplet geometry w…
Dynamic Viscosity of Methane and Carbon Dioxide Hydrate Systems from Pure Water at High-Pressure Driving Forces
André Guerra, Adam McElligott, Chong-Yang Du +3
The viscosity of methane and carbon dioxide hydrate systems were measured using a high-pressure rheometer up to 30 MPag. Where hydrate formation was not detected, the effect of tem…
Molecular dynamics predictions of transport properties for carbon dioxide hydrates under pre-nucleation conditions using TIP4P/Ice water and EPM2, TraPPE, and Zhang carbon dioxide potentials
André Guerra, Samuel Mathews, Jennifer Tram Su +3
(1) Introduction: New technologies that leverage gas hydrates phenomena include carbon capture and sequestrations. These processes are often semi-continuous and require regulation…
