A study of adiabatic and diabatic flow boiling in parallel microchannels and fractal-like branching microchannels

Creator:: Daniels, Brian J.
Abstract:: A one-dimensional numerical model has been developed to study diabatic and adiabatic flow boiling in microchannels. This model accounts for developing flow effects and variable property effects. The model uses correlations for void fraction and two-phase multipliers found in the literature. The model has been used to study the performance...

A study of the characteristics of oscillatory surface instabilities leading to droplet formation

Creator:: Daniels, Brian J.
Abstract:: The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...

Advancing forced draft biomass cookstove technology with computational fluid dynamics modeling

Creator:: Cassidy, Liam J
Abstract:: Today, billions of people are limited to using biomass-fueled traditional fires as a primary energy source for cooking and purification of drinking water. Reliance on open burning of biomass leads to exposure to high levels of household air pollution which has been estimated to claim over 1.5 million lives annually,...

An approach to reduced-order modeling and feedback control for wave energy converters

Creator:: Shoori J., Hesam E.
Abstract:: Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

Creator:: Sharp, Christopher J.
Abstract:: Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

Effect of hydrous ethanol on crankcase oil dilution

Creator:: Khalifa, Gamaleldin A.
Abstract:: Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...

Student Club Analysis: The Effects of Organizational Structuring on Competition Performance

Creator:: Chandler, Jacob J.
Abstract:: This thesis aims to explore the effects of organizational and management principles within the context of a student club – an international Formula Student team. Research on the effects of organizational structuring on student club performance tends to be qualitative in nature. While considering the inherent complexity of the human...

The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

Creator:: Dimas-Harms, Colton R.
Abstract:: In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...

Natural convection and conduction in a vertical annulus with a concentric baffle : a numerical study

Creator:: Fishbaugher, Mark J.
Abstract:: Analytical and numerical study of steady-state laminar natural convection and conduction has been performed for an enclosure between concentric vertical cylinders. The inner and outer cylinders were isothermal, and the connecting top and bottom walls were adiabatic. A concentric baffle was included in the annulus, and the flow field and...

Polycarbonate as a photoplastic stress freezing material

Creator:: Broderick, John Justin
Abstract:: Dead weight creep tests were conducted on polycarbonate in order to determine if it is a linear viscoelastic material; or if it is not, then to determine the feasibility of photoplastic stress freezing. Secondary objectives were: the determination of the parameters in the creep compliance of a four element viscoelastic...
