Study of a constrained-film bubble absorber under cycle operating conditions

Creator:: Cardenas, Ruander
Abstract:: An experimental and numerical study of absorption of ammonia vapor bubbles into a constrained thin film of ammonia-water solution is presented in the context of a potential reduction in size of a heat-actuated heat pump component. A large-aspect-ratio channel with a depth of 600 µm restricts the thickness of the...

Reduced condensing pressure operation in industrial ammonia refrigeration systems

Creator:: Wilcox, Marcus H.
Abstract:: A computer model was created using compressor and condenser performance data to simulate vapor-compression ammonia refrigeration system performance under various operating conditions and strategies. The model was used to estimate energy, demand, and cost savings resulting from reduced condensing pressures. Two ammonia refrigeration systems were selected for the investigation into...

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...

Resource Type:: Dissertation

A study of compression loading of composite laminates

Creator:: Berbinau, Pierre J.
Abstract:: The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

An experimental investigation of heat transfer in the transition and turbulent regimes for natural convection in mercury in a uniformly heated vertical channel

Creator:: Humphreys, William Warren
Resource Type:: Masters Thesis

Kinematics of arthropod legs : modeling and measurement

Creator:: Albright, Stephen L.
Abstract:: This thesis presents a method for determining the kinematic geometry of arthropod legs. A kinematic description makes possible the analysis of arthropod leg motion, as a prelude to investigating how various arthropod species are able to negotiate diverse terrains. Such knowledge will aid in design of legged vehicles. The focus...

An optimal design method for an air-heating solar energy collector

Creator:: Grill, Alan Richard
Abstract:: Some desirable features of a solar energy collector are listed and a collector design is presented which incorporates their features. As the collector is operated, air flows within the collector enclosure and is heated as it passes through a porous radiant energy receiver mounted in the enclosure. The porous energy...

An experimental study of natural convection in air between a vertical isothermal flat plate and a parallel insulted flat plate

Creator:: Lee, Soon Mo
Abstract:: The free convective heat transfer phenomena in air between two vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the other adiabatic. A quartz fiber anomometer was used for measuring local velocities in the air between the vertical...
