Measurements and Modeling of Coal Ash Deposition in an Entrained-Flow Reactor
… for a commercial comprehensive combustion and CFD code. Results from the new submodel and CFD code is are then compared to deposition measurements in on a simulated boiler tube where particle mass deposited and ash size distribution are measured. Several model components governing various …

Modeling buoyancy-driven airflow in ventilation shafts
… shafts. These improvements are validated by Computation Fluid Dynamics (CFD) models that haven been validated by small scale and full scale experiments. The full scale experiment provides a detailed data set of an actual atrium that can be used in further validations and demonstrates the …

Constrained Control for Helicopter Shipboard Operations and Moored Ocean Current Turbine Flight Control
… sea-based conditions. A complex helicopter-ship dynamics interface has been developed as a system of implicit nonlinear ordinary differential equations to capture essential characteristics of the nonlinear helicopter dynamics, the ship dynamics, and the ship airwake interactions. Various airwake …

Using remote sensing to track resilience of subtropical rainforests against fires and tropical cyclones
… provided new tools to study forest-disturbance dynamics across unprecedented spatiotemporal scales. In this thesis, a range of high-resolution remote sensing products, including aerial imagery, satellite multispectral imagery, and airborne LiDAR scans, were used to evaluate how fires and …

Development of a liquid drug delivery payload for modular, wireless, incorporeal robots for laparoscopic surgery
Minimally invasive abdominal surgery (laparoscopy) is performed using long, slender instruments inserted through multiple small incisions in the patient's abdominal wall. This results in less post--operative pain, shorter hospital stays, and a quicker return to normal activities for the patient …

Effects of operating and geometric variables on hydrodynamics and tablet dissolution in standard and modified dissolution testing apparatuses 2
… large body of work, some key aspects of the hydrodynamics of Apparatus 2 have received very little attention, such as the determination of its power dissipation requirements (which controls solid-liquid mass transfer processes) and the velocity distribution under the different agitation conditions …

Cavitation in Pharmaceutical Manufacturing and Shipping
… at the University of Denver demonstrated that fluid cavitation can generate a large number of sub-visible protein particles in ultra clean formulations, but that mitigation can be achieved with fluid property manipulation. The goal of this research was to (1) assess the risk of cavitation under …
