Fine Line Metallization of Silicon Heterojunction Solar Cells via Collimated Aerosol Beam Direct Write
(North Dakota State University, 2012)
Solar energy has come to the forefront as a scalable and largely underutilized renewable energy resource. The current cost of solar electricity, namely from photovoltaics, along with other logistics factors, has prevented ...
Numerical Simulation of Direct Expansion Solar-Assisted Heat Pump Water Heater Using Carbon Dioxide as Refrigerant
(North Dakota State University, 2013)
Compared to the conventional solar-assisted heat pump (SAHP) water heating system, a relatively more compact direct-expansion solar assisted heat pump (DX-SAHP) has been introduced, in which the solar collector acts as an ...
Numerical Analysis of a PV/Microchannel Integrated CO2 Direct-Expansion Heat Pump Water Heater
(North Dakota State University, 2019)
A steady-state numerical model of a PV/microchannel integrated direct-expansion CO2 heat pump (PV-DXHP) water heater is developed, validated, and analyzed in the present study. To accomplish the objectives, a numerical ...
Experimental Investigation of the Temperature Effects on the Behavior of Adhesively-Bonded Dissimilar Materials
(North Dakota State University, 2017)
The effects of temperature on the fatigue and low velocity impact (LVI) behaviors of adhesively-bonded single-lap joints (SLJs) composed of a pultruded E-glass/polyurethane composite bonded to 5052 aluminum and A36 steel ...
Method for Compliance Controlled Adhesive Switching and Magnetically Controlled Switchable Adhesives
(North Dakota State University, 2013)
Adhesives are used in a variety of ways and are so common that they are easily overlooked. Adhesive hooks, tapes, glues, and switchable climbing mechanisms used by insects and lizards are clear examples of how adhesives ...
Fatigue Analysis of Arteries Using Finite Element Method
(North Dakota State University, 2012)
In this thesis, the fatigue response of arteries to four specific physiological conditions representative of various morphological changes that artery undergo during its lifetime, was explored. Single layered nonlinear ...
High-Performance Simulations for Atmospheric Pressure Plasma Reactor
(North Dakota State University, 2012)
Plasma-assisted processing and deposition of materials is an important component of modern industrial applications, with plasma reactors sharing 30% to 40% of manufacturing steps in microelectronics production [1]. Development ...
Development of an Anti-Corrosion Thermally Sprayed Coating System for Oil and Gas Transmission Pipeline
(North Dakota State University, 2018)
Corrosion, a leading cause of failure in metallic transmission pipelines, significantly impacts the reliability and safety of metallic pipelines. To prevent and mitigate pipeline corrosion, various non-metallic coatings ...
Nonlinear Fatigue Damage Accumulation in Aircraft Engine Alloys Multiaxial Loading
(North Dakota State University, 2013)
Fatigue is considered to be one of the most frequent phenomena in the failure of many
machine parts. Most of the prior studies on fatigue have been limited to uniaxial loading cases
with a primary focus on constant ...
Characterizing the Operation of a Dual-Fuel Diesel-Hydrogen Engine near the Knock Limit
(North Dakota State University, 2014)
A CAT C6.6 turbocharged diesel engine was operated in dual-fuel diesel-hydrogen mode. Hydrogen was inducted into the intake and replaced a portion of the diesel fuel. Hydrogen was added across multiple engine speeds and ...
