The Physico-Chemical Investigation of Interfacial Properties in Natural Fiber/Vinyl Ester Biocomposites
(North Dakota State University, 2012)
Bast fibers are one of most widely used types of cellulosic natural fibers. Flax fibers, a specific type of bast fiber, have historically been used as reinforcements in composites because they offer competitive advantages, ...
Experimental Characterization of Aerosol Flows Through Micro-Capillaries
(North Dakota State University, 2012)
Understanding the forces which dictate fluid particle interaction is of high interest in the field of aerosol jet Direct Write (DW). Several methods utilizing shadowgraphy and Mie scattering were used to visualize particle ...
Microstructural Characteristics and Mechanical Behavior of Anticorrosive Al-Zn Thermal Spray Coatings Deposited by Wire Arc Spraying and Cold Spraying Techniques
(North Dakota State University, 2019)
Mechanical properties of thermal spray deposited coatings are highly influenced by their microstructural characteristics. The objective of this investigation is to evaluate the mechanical properties of thermally sprayed ...
Lubrication and Wear at Metal/HDPE Contacts
(North Dakota State University, 2012)
In the thesis lubrication and wear at metal/HDPE contacts was addressed. In particular this type of contact occurs in artificial joint replacements. Wear of HDPE was recognized as a major factor limiting device performance.
In ...
Computational Simulations of Compressible Transitional Flows in a Turbine Vane Cascade
(North Dakota State University, 2019)
In order to improve the efficiency and reduce the emissions of aircraft engines, new combustor designs have been developed to reduce outlet temperatures and increase mixing. At high altitudes, the low pressure and low ...
Experimental Use of Hydrogen to Reduce the Consumption of Carbon Fuels in a Compression Ignition Engine and Its Effect on Performance
(North Dakota State University, 2016)
As part of an effort to find use for electric energy produced by wind turbines, Basin Electric started a program to produce hydrogen through electrolysis. It is not enough to simply produce hydrogen, there needs to be uses ...
Ultra-Violet Degradation Behavior of Polymeric Backsheets of Photovoltaic Modules
(North Dakota State University, 2014)
This study is designed to understand the ultra-violet (UV) degradation of polymeric backsheets used in PV modules. Commercial photovoltaic backsheets from four suppliers were UV-aged for up to 3000 hours. The aged samples ...
Design and Fabrication of Micro-Channels and Numerical Analysis of Droplet Motion Near Microfluidic Return Bends
(North Dakota State University, 2019)
Three-dimensional spheroid arrays represent in vivo activity better than conventional 2D cell culturing. A high-throughput microfluidic chip may be capable of depositing cells into spheroid arrays, but it is difficult to ...
A Single-Cylinder Internal Combustion Engine Test Unit for the Engineering Laboratory
(North Dakota State University, 1962)
The study of the reciprocating internal combustion engine is of prime importance to the student engineer. In our present civilization, the number of units and the total rated power of internal combustion engines in use is ...
Optimized Evaluation of Bone Tissue Material Properties by Inverse Finite Element Analysis and Femur Fracture Testing
(North Dakota State University, 2015)
The main objective of this research is to characterize bone inhomogeneous elastic, yield, and post-yield behaviors, using a computational-experimental approach. The current study uses the force-displacement results of one ...
