Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

Creator:: Tost, Brian C.
Abstract:: This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...

Laminate mixing in microscale fractal-like merging channel networks

Creator:: Enfield, Kent E.
Abstract:: A two-dimensional model was developed to predict concentration profiles from passive, laminar mixing of concentration layers formed in a fractal-like merging channel network. Both flat and parabolic velocity profiles were used in the model. A physical experiment was used to confirm the results of the model. Concentration profiles were acquired...

An aeroelastic analysis of the Darrieus wind turbine

Creator:: Meyer, Edward Earnest
Abstract:: The stability of small oscillations of the troposkeinshaped blade used on Darrieus wind turbines is investigated. The blade is assumed to be attached to a perfectly rigid rotor shaft and spinning in still air. Linear equations of motion are derived which include the effects of in-plane, out-of-plane, and torsional stiffness,...

Dynamic modeling of a refrigerant boiler for power applications

Creator:: Curry, Thomas Haitsch
Abstract:: A dynamic model of a refrigerant boiler has been produced by the use of distributed parameter modeling techniques. A number of elementary cases were studied and were used as an aid in the final model formulation. Modeling using distributed parameters employed the use of mesh equations which were then reorganized...

Transient fuel pin temperature calculations using describing functions

Creator:: Guidotti, Timothy E.
Abstract:: An important element in rector safety and fuel performance assessments is the efficient calculation of the time dependent temperature profiles within reactor fuel pins. Because the fuel pins have temperature dependent thermal properties, the governing partial differential equations are nonlinear. Traditionally, finite difference or finite element methods have been used...

Evaluation of system-level performance of closed thermochemical energy storage systems for space heating

Creator:: Rivera, Kate E.
Abstract:: This study evaluates the system efficiency and energy-offsetting capabilities of a closed-cycle thermochemical energy storage (TCES) system. Current TCES research primarily focuses on material selection and reactor design but overlooks the practical limitations faced on a system level. Thus, this study investigates various TCES integration methods for providing building space...

Stagnation point heat transfer in a relaxing gas

Creator:: Wilson, Robert E.
Abstract:: Stagnation point heat transfer in a gas undergoing relaxation of its internal energy is examined by solution of the equations of motion using the two temperature approach of Wang Chang and Uhlenbeck. The results are presented in parametric form and show that relaxation effects produce an adiabatic wall temperature above...

A portable pumping system for hydraulic excavation of commercial crab pots

Creator:: Chang, Terrill John
Abstract:: The design and testing of a portable pumping system for use in the hydraulic excavation of commercial crab pots buried by ocean sediment was undertaken. The resulting portable system retained the four major components of the pumping systems presently used by commercial fishermen: engine, pump, fire hose, and nozzle. Because...
