Dynamics of Compound Droplets via 3D Spectral Boundary Elements
(North Dakota State University, 2013)
Compound droplets raise great interests due to their applications in the pharmaceutical, cosmetic, and food industry. In spite of the growing demand of theoretical investigation of dynamics of compound droplets from those ...
An Experimental Study on a Density Driven Solar Water Heating System Using Supercritical CO2 as Working Fluid
(North Dakota State University, 2013)
For supercritical carbon dioxide, a small change in temperature or pressure can result in large change in density, especially close to its critical point. At this pseudocritical region, density decreases rapidly with ...
Numerical Studies of Droplet Behavior in a Steady Non-Uniform Electric Field
(North Dakota State University, 2013)
An initially uncharged droplet suspended in another immiscible fluid under the influence
of a steady non-uniform electric field may experience deformation, migration and bursting.
This work numerically investigated the ...
Numerical Simulation of Direct Expansion Solar-Assisted Heat Pump Water Heater Using Carbon Dioxide as Refrigerant
(North Dakota State University, 2013)
Compared to the conventional solar-assisted heat pump (SAHP) water heating system, a relatively more compact direct-expansion solar assisted heat pump (DX-SAHP) has been introduced, in which the solar collector acts as an ...
Method for Compliance Controlled Adhesive Switching and Magnetically Controlled Switchable Adhesives
(North Dakota State University, 2013)
Adhesives are used in a variety of ways and are so common that they are easily overlooked. Adhesive hooks, tapes, glues, and switchable climbing mechanisms used by insects and lizards are clear examples of how adhesives ...
Nonlinear Fatigue Damage Accumulation in Aircraft Engine Alloys Multiaxial Loading
(North Dakota State University, 2013)
Fatigue is considered to be one of the most frequent phenomena in the failure of many
machine parts. Most of the prior studies on fatigue have been limited to uniaxial loading cases
with a primary focus on constant ...
Theoretical and Experimental Studies of Droplets Wetting on Micronano-Fibrous Materials and their Applications in Oil-Water Separation
(North Dakota State University, 2013)
This research was aimed at the theoretical and experimental investigation of wetting behavior of immiscible droplets sitting on filaments and related applications in oil-water separation. This work consisted of three ...
Mechanical Analysis of Polycarbonate/Polysiloxane Block Copolymers and Blends
(North Dakota State University, 2013)
Polydimethylsiloxane (PDMS) can be used to react with polycarbonate (PC) to generate PC-PDMS multiblock copolymers and PC/PC-PDMS-PC triblock blends to overcome the notch sensitivity of PC while maintaining its transparency. ...
Nanomechanical Characterization of Tobacco Mosaic Virus Superlattice with Novel Atomic Force Microscopy Methods
(North Dakota State University, 2013)
Tobacco mosaic virus (TMV) has been widely studied due to its excellent properties. In order to utilize TMV superlattice, this thesis initiates the study on its mechanical properties. The elastic modulus of TMV superlattice ...
Characterization of Mechanical Properties in Hybridized Flax and Carbon Fiber Composites
(North Dakota State University, 2013)
Natural fiber composites have been found to exhibit suitable mechanical properties for general applications. However, when high strength applications are required, natural fibers are typically not considered as a practical ...
