A detailed formulation of the momentum equation
including the Baroczy model for two phase friction is
presented in this thesis. Numerical techniques for solving
this equation along with the remainder of the describing
equations are also presented. This model has been
incorporated into an existing thermal hydraulic code for
simulating...
Current technological shortcomings limit the economic viability of capturing and utilizing small sources of methane. The development of a reactor to overcome these limitations would unlock economic opportunity and incentivize reduced methane emissions. A microfluidic bioreactor containing immobilized methanotrophs has the potential to overcome these limitations by profitably converting small...
A method is presented for appraising the hazards to nuclear
power plants from missiles from surface traffic accident explosions.
Due to the infrequency with which surface traffic accident explosions
occur and the poor records kept concerning them, a probabilistic
method is chosen to investigate the overall hazards potential to
nuclear...
A vital safety concern in the analysis of nuclear power reactors
is the thermal hydraulic behavior of the reactor coolant system
under steady state and transient conditions. The goal of this
study has been to develop an appropriate model for the U-tube type
steam generators in a typical pressurized water...
The goal of this study is the modeling of a postulated break
of the steam line at the containment penetration of the Trojan
Nuclear Plant which is owned and operated by Portland General
Electric. To perform this modeling, the RETRAN computer code
package was utilized. RETRAN is designed to provide...
In the U.S. there are increasing energy demands that require an ever-increasing need for the large-scale use of new energy resources. Specifically, sporadic renewable energy sources are being incorporated into utility energy portfolios. Thus, supporting stationary energy storage technologies are needed to make these renewable sources reliable and feasible for...
Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...
The demand from consumers for more sustainable products, and the need to comply with government regulations motivates manufacturers to evaluate their operations for opportunities to reduce environmental impact and improve economic competitiveness. Manufacturers have actively improved the sustainability performance of their products through the use of sustainability assessment methods and...
Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...
