Numerical Simulation and Structural Optimization of Composite Rigid Frame Bridge
(North Dakota State University, 2017)A composite rigid frame bridge replaces a certain portion of the concrete middle span of a bridge with a section of the steel girder. While the steel span improves the bending moment distribution of the rigid frame structure, ... -
Numerical Simulation of a Direct Expansion Geothermal Heat Pump Using Carbon Dioxide in a Transcritical Cycle
(North Dakota State University, 2011)Many of the synthetic refrigerants used in heat pump and air conditioning systems are potent greenhouse gases. In light of the increasing concern regarding climate change, there has been an increased interest in natural ... -
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 ... -
Numerical Simulations of Electrohydrodynamic Evolution of Thin Polymer Films
(North Dakota State University, 2015)Recently developed needleless electrospinning and electrolithography are two successful techniques that have been utilized extensively for low-cost, scalable, and continuous nano-fabrication. Rational understanding of the ... -
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 ... -
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 ... -
A Numerical Study and Optimization of a Morphing and Pitching Boeing Vertol VR-12 Rotorcraft Airfoil
(North Dakota State University, 2022)The helicopter blade has not undergone any major change in design in recent history, only minor adjustments like swept blade tips, variable twist blade, and application of small gurney flap style trailing edge devices. ... -
