Experimental Studies of Pulsatile Flow Passing Side Wall Biological Cavities and Flow Enhancement Using Hydrophobic Surfaces
(2020)
Understanding the hemodynamics of the cardiovascular system and associated diseases is important for mitigating health risks. We applied flow diagnostic techniques to investigate pulsatile flow characteristics past sidewall ...
Short Glass Fiber Reinforced Composites Manufactured by Stereolithography
(North Dakota State University, 2021)
The effectiveness of manufacturing short glass fiber composites using stereolithography (SLA) was investigated. Modifications were made to a standard SLA printer to induce a flow field through the resin tank. In this study ...
Experimental Investigation of Shear Thickening Fluid Impregnated Flax Fabric and Flax/Kevlar Hybrid Fabrics
(North Dakota State University, 2020)
Shear thickening fluids have the potential to improve the effectiveness of fabric materials in body armor applications as they have shown to increase the puncture and ballistic resistance of Kevlar fabrics. However, the ...
Dynamic Stall Characteristics of Pitching Finite-Aspect-Ratio Wings
(North Dakota State University, 2021)
In this study, an experimental investigation was performed to characterize the dynamic stall of pitching wings and provide confirmation of the existence of the arch-shaped vortex for moderate sweep wing. Dynamic stall is ...
Simulation-Based Optimization and Artificial Intelligence Techniques for Macromechanical and Micromechanical Characterization of Soft Biological Tissues
(North Dakota State University, 2021)
Traumatic brain injury (TBI) is a serious health and socioeconomic issue which affects thousands of lives annually in the United States. Computational simulations play an important role in better understanding of the TBI ...
The Effects of Surface Roughness on the Functionality of Titanium Based Alloy Ti13Zb13Zr Orthopedic Implants
(North Dakota State University, 2021)
In this study, the effects of surface roughness on the wettability, cell attachment, and mechanical properties of titanium-based Ti13Nb13Zr orthopedic implants have been investigated. The aim of this multidisciplinary ...
Increasing Cotton Product/Waste Value Through New Use Development
(North Dakota State University, 2021)
Cotton products have been used for centuries with relatively low value and their ubiquitous use generating large quantities of waste materials. This research’s goal was to develop new uses for waste cotton fiber and ...
Mechanics of Surface Instabilities of Soft Nanofibers and Nonlinear Contacts of Hydrogels
(North Dakota State University, 2020)
The research of this dissertation is formulated in two fields, i.e., the theoretical and computational studies of circumferential wrinkling on soft nanofibers and the swelling mechanics study of a bi-layered spherical ...
Computational Simulations of Flow Past a Rotating Arrangement of Three Cylinders Using Hybrid Turbulence Models
(North Dakota State University, 2020)
Over the past 25 years, advances in the field of turbulence modeling have been made in an effort to resolve more scales, preserving unsteadiness within a flow. In this research two hybrid models, Scale-Adaptive Simulation ...
Atomic Force Microscopy-Based Nanomechanical Characterization of Kenaf Microfiber and Cellulose Nanofibril
(North Dakota State University, 2021)
Kenaf fiber is increasingly getting the attention of the industries due to its excellent mechanical properties, feasibility, growth rate, and ease of cultivation. On the other hand, cellulose nanofibril is one of the ...
