Best Practices in Computational Fluid Dynamics Modeling of Cerebral Aneurysms using ANSYS CFX
(North Dakota State University, 2015)
Today many researchers are looking toward computational fluid dynamics (CFD) as a tool that
can help doctors understand and predict the severity of aneurysms, but there has yet to be any
conclusive proof of the accuracy ...
Numerical Investigation of Vibration in a Steam Turbine Control Valve
(North Dakota State University, 2017)
A numerical analysis is performed at North Dakota State University to investigate and resolve steam inlet control valve vibration in a Minnkota Power Cooperative turbine. Pressure fluctuations resulting from an unstable ...
Simulation of a Sudden Expansion Using Axis Symmetric Modeling for Newtonian Blood Flow
(North Dakota State University, 2014)
This paper examines the flow of a Newtonian modeled blood through axisymmetric sudden expansion geometry. Reynolds number of 500, 2000, 3500, 5000, and 6500 are examined using laminar, shear stress transport, and base line ...
Numerical Simulations of Incompressible and Compressible Transitional Turbine Flows
(North Dakota State University, 2014)
Accurate and reliable turbulence and transition models are needed for prediction heating loads in the hot section of the turbine, and predicting aerodynamic losses when designing new blade profiles. Two dimensional ...
The Use of Electrospun Soy Protein Isolate/Polyvinyl Alcohol Nanofibers for Controlled Drug Delivery As Well As Investigation Into Mass Production
(North Dakota State University, 2015)
As the global movement progresses towards environmental awareness, industries are attempting to become less dependent on petroleum based materials. This study investigates the incorporation of Soy Protein Isolate (SPI) ...
Bioprinting of Pancreatic Cancer Cells for Improved Drug Testing
(North Dakota State University, 2019)
Currently, many drugs are preclinically tested on two-dimensional cell cultures. However, this method does not adequately replicate the cellular interactions or diffusion gradient that occur in three-dimensional tissues, ...
Evaluation of Mechanical Properties of Al-Cu Cold Sprayed and Alloy 625 Wire Arc Sprayed Coatings
(North Dakota State University, 2014)
This study examines microstructural-based mechanical properties of Al-Cu composite deposited by cold spraying and wire arc sprayed nickel-based Alloy 625 coating using numerical modeling and experimental techniques. The ...
Assessment of Native Aortic Stenosis Hemodynamics and Clinical Evaluation Methods Using Steady State Computational Fluid Dynamics and Computed Tomography-Derived Geometry
(North Dakota State University, 2012)
Aortic stenosis is the most common valvular heart disease with a prevalence of 2% among individuals over 65 years and 4% over 80, in developed countries. Accurate valve assessment for intervention timing is critical. Using ...
Computational Biomechanics of Blast-Induced Traumatic Brain Injury: Role of Loading Directionality, Head Protection, and Blast Flow Mechanics
(North Dakota State University, 2015)
In this dissertation, blast-induced traumatic brain injury (bTBI) is studied with respect to
the blast wave directionality, mitigation capability of helmet/faceshield, and blast flow
mechanics using finite element (FE) ...
Impact of Recycling on the Mechanical and Thermo-Mechanical Properties of Wood Flour/High Density Polyethylene and Wood Flour/Poly Lactic Acid Composites
(North Dakota State University, 2016)
This research concentrates on the recyclability of two wood plastic composites (WPCs) - wood flour/HDPE and wood flour/PLA composites. Two different filler loadings (30 and 50 wt%) were considered for each polymer composite. ...
