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 ...
Micromechanical Characterization of Brain White Matter with Bi-Directional Orientation of Axonal Fibers
(North Dakota State University, 2015)
Axonal injury within the white matter of human brain and spinal cord has led to several diseases in the Central Nervous System (Karami and Shankar, [1]). Diffuse axonal injury, one of the forms of Traumatic Brain Injury ...
Improving Performance Characteristics of Poly (Lactic Acid) (PLA) Based Nanocomposites by Enhanced Dispersion of Modified Cellulose Nanocrystals (CNCs)
(North Dakota State University, 2018)
Poly(lactic acid), (PLA) is a biodegradable and biocompatible polymer which has attracted significant attention as a promising substitute for petroleum-based polymers. To optimize the usage of PLA in a wide range of ...
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 ...
