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 ...
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 ...
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 ...
Modal Analysis of the Human Brain Using Dynamic Mode Decomposition
(North Dakota State University, 2020)
The human brain is the most important organ of the human body. It controls our thoughts, movements and emotions. For that reason, protecting the brain from harm is of the utmost importance but to protect the brain, one ...
Generation and Analysis of Streamwise Vortices from Vortex Tube Apparatus
(North Dakota State University, 2020)
A pressurized vortex tube is used to generate streamwise vortices in a wind tunnel and the resulting flow behavior is analyzed. The apparatus is intended to verify computational data from the AFRL by offering a method of ...
Advanced Measurements and Analyses of Flow Past Three-Cylinder Rotating System
(North Dakota State University, 2020)
Interaction of flow structures from a three-cylinder system is complex and important for fundamental and engineering applications. In this study, experiments using hotwire, 2D PIV, and Tomography are to be conducted to ...
Experimental Study of Effects of Leading-Edge Structures on the Dynamic Stall of a Vertical Axis Wind Turbine Airfoil
(North Dakota State University, 2020)
Vertical axis wind turbine, developed as one of the main methods to utilize the wind energy, has a promising future; however, the major issue to limit its performance is the uneven loading on the blade during operation. ...
Device Design for In-Situ EIS Measurements of Organic Coatings Under Accelerated Degradation Via Impingement Flow
