Penumbra : A Spatiotemporal Shade-Irradiance Analysis Tool with External Model Integration for Landscape Assessment, Habitat Enhancement, and Water Quality Improvement

Creator:: Halama, Jonathan James
Abstract:: Several solar energy models exist, but all models must balance: computational runtime, light complexity, and model output volume. These models span the spectrum of simplistic global solar energy equation sets to complex light ray-tracing models. Spatiotemporally inaccurate representations of solar energy may cause compounding simulation effects and introduce unknown modeling...

Volumetric receiver development : a heat transfer and design evaluation of an advanced air heating solar thermal central receiver concept

Creator:: Drost, M. K.
Abstract:: The volumetric receiver is an advanced solar central receiver concept designed to produce high temperature air. This document presents the results of a heat transfer and performance evaluation of the volumetric receiver concept. The volumetric receiver consists of an array of ceramic fins or fibers arranged in concentric rows around...

The spatial-scale dependence of the observed anisotropy of reflected and emitted radiation

Creator:: Ye, Qian
Abstract:: The Earth Radiation Budget Experiment (ERBE) uses Angular Dependence Models (ADMs) to convert satellite observed radiances to radiative fluxes at the top of the atmosphere. Owing to errors in scene identification and to the relationship between the spatial scales of cloud systems and the spatial resolution of the ERBE scanner,...

Analysis of domain decomposition methods for the simulation of charge transport in semiconductor structures with heterojunctions

Creator:: Costa, Timothy B.
Abstract:: Charge transport in a semiconductor structure with heterojunction is described by a multiscale partial differential equation model. This model can be used, e.g., for the design of more efficient solar cells. Phenomena at the heterojunction must be resolved at the angstrom scale while the size of the device is that...

Inorganic thin-film solar cells

Creator:: Spies, Jack Alexander
Abstract:: The primary objective of this thesis is to explore new absorber and p-type window layer materials for thin-film solar cell applications. A new thin-film electron beam deposition system has been installed, is now operational, and has been used to deposit several types of solar cell absorber layers. Material investigations include...

A high power emulation of a wind farm

Creator:: Lalla, Chelsea
Abstract:: As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and...

Computer simulation of transient refrigeration load in a cold storage for apples and pears

Creator:: Adre, Norberto
Abstract:: Increased consumer demand for fresh fruit throughout the year has created a need for long term storage. Long term storage of fruit uses more energy than fresh market products, thus increasing production cost. Pacific Northwest energy costs and more competition for markets has made energy conservation an important factor to...
