Effect of hydrous ethanol on crankcase oil dilution

Creator:: Khalifa, Gamaleldin A.
Abstract:: Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...

Design and optimization of a heating-only heat pump for Western Pacific Northwest applications

Creator:: Elger, Donald Francis
Abstract:: The use of the conventional air-source heat pump for residential space conditioning has increased dramatically over the past decade. Historically these units have been designed as air conditioners which could also be used to provide heating. However, for the climatic region of the Western Pacific Northwest (the geographic region west...

Analysis of ice formation with flow reversal for application to an ice-maker heat pump

Creator:: Aceves, Salvador M.
Abstract:: The problems of freezing and melting present special mathematical complexity and, except for the most elementary one-dimensional cases, require a numerical solution. However, these problems have a growing importance in engineering problems because of their application to metallurgical operations, food preservation, heating and air conditioning, etc. In the present work,...

A two-group study on the gadolinium particle depletion in light water reactor fuel rods

Creator:: Lee, Chungchan
Abstract:: The effect of gadolinia particles on the assembly criticality of a light water reactor was investigated using two 2-group models. The particle effect was calculated by comparing the criticalities of two fuel assemblies, each containing one gadolinia-poisoned rod. For purposes of comparison, both rods contained an equal quantity of gadolinia,...

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...

Evaporator analysis for application to water-source and ice-maker heat pumps

Creator:: Aceves, Salvador M.
Abstract:: Water-source and ice-maker heat pumps share many characteristics. However, each presents different technical difficulties that have prevented them from being used more widely. In a water-source heat pump a very important consideration is to reduce water consumption, while in an ice-maker heat pump a major concern is to reduce the...

A theoretical and experimental study of self-propagating high-temperature synthesis of titanium carbide

Creator:: Huque, Ziaul
Abstract:: Self-propagating high-temperature synthesis (SHS) is a new method of producing advanced ceramic materials and offers an attractive alternative to conventional methods of materials processing. An experimental investigation was carried out to determine the SHS reaction wave propagation speed in a vertical cylindrical compact made from a mixture of titanium and...

Computational modeling of Lorentz force induced mixing in alkali seeded diffusion flames

Creator:: Thompson, Jon Ira
Abstract:: Lorentz forces provide a unique method for the control and mixing of gas flows without the physical intrusion of objects into the flow. Lorentz forces arise when an electric current is passed through a volume in the presence of a magnetic field. The interaction between the electric current and the...

Fully developed laminar natural convection in a vertical parallel-plate duct with constant wall heat flux

Creator:: Aktan, Gülçin
Abstract:: The problem of heat transfer due to free convection in a channel formed by two parallel, isoflux, vertical plates is of considerable importance in electronic cooling applications, thermosiphons, the optimum spacing of plates or components, industrial stacks, heat exchangers, nuclear power plants and combustion involving vertical walls. Although in each...
Resource Type:: Masters Thesis

Coupled dynamics of bouys and mooring tethers

Creator:: Idris, Krisnaldi
Abstract:: Time-domain models were developed to predict the response of a tethered buoy subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and its mooring is included and three-dimensional response is assumed. External loadings include hydrodynamic forces, tethers tensions, wind loadings and the weight of both cable...
