Experimental Investigation of Near-Critical Carbon Dioxide in Microchannels for High Flux Cooling Applications

Creator:: Travers, Kristen
Abstract:: With the continued decrease in size and subsequent increase in power of computer processors, thermal management in electronics is becoming more important than ever before. The chip heat densities are reaching new peaks (> 100 W cm-2) that current cooling methods are not able to keep up with. However, some...

Melting Stage Analysis for Indirect Freeze Desalination

Creator:: Pratt, Mason G.
Abstract:: To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, ﬁrst, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The ﬁrst...

Development of a Mobile Application for Android Platforms

Creator:: Hayden, Levi G.
Abstract:: The ability to develop mobile applications for smartphones and tablets is an increasingly valuable skill in today’s labor market. This thesis details the development of the mobile application Drone Drop from beginning to finish. I first describe the background research conducted to learn about programming languages and other tools used...

Trailing Edge Flap Optimization for an Upper-Surface Blown Aircraft Wing

Creator:: Kelly, Bryan R.
Abstract:: Integrated Distributed Electric Augmented Lift (IDEAL) applies upper surface blowing in a novel way to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on propulsion airframe interaction (PAI) with trailing edge flaps at low Reynolds numbers was necessary to advance the...

Part-Load Optimization of an Organic Rankine Cycle

Creator:: Ramsey, Owen
Abstract:: Waste-heat-recovery Organic Rankine Cycle (ORC) systems use excess heat from industrial processes to produce electrical power. In many cases, the temperatures and mass flow rates of these excess-heat streams vary significantly over time, causing the ORC to often operate far from its design point. In this study, a control strategy...

A Field Study on Marching Band Members' Workload Assessment

Creator:: Wells, Robyn R.
Abstract:: Marching band activities consist of both physically and cognitively demanding tasks. The demands that this activity has on players has largely been unstudied. The goal of this study was to investigate the effects of players’ experience level, role, and gender on the workload of marching band players via a field...

Effects of thermal stressing on the turbulent flame speed of jet fuel

Creator:: Alkhalifa, Ammar M.
Abstract:: Gas turbine engines for propulsion applications can use fuel as a coolant, exposing the fuel to high temperatures well within the ranges associated with thermal decomposition. Species produced as a result of these processes have been shown to correlate with changes in the combustion performance of the fuels. In this...

Identification of Barriers to Industrial Energy Efficiency Improvement in the Pacific Northwest

Creator:: Martz, Allison M.
Abstract:: The US industrial sector accounts for about one-third of the nation’s energy consumption and is predicted to grow twice as quickly as other sectors through 2050. International organizations such as the International Energy Agency project energy efficiency improvements will account for over 40% of greenhouse gas emissions reductions through 2040....

Preserving the Planar Dynamics of a CompliantBipedal Robot with a Yaw-Stabilizing Foot Design

Creator:: Abate, Andrew M.
Abstract:: The ATRIAS agile humanoid robot, along with a number of other spring-mass walking machines, currently have two instabilities: one resulting from inertial forces on the torso which cause the robot to spin like a top, and another resulting from stiff ground collisions which cause chattering of the point-contact toes. This...

Development of a Framework for Analyzing the Effects of a Micro Pin Fin Array on the Catalytic Combustion of Hydrogen in Micro-channels

Creator:: Walters, Eric M.
Abstract:: An experimental framework for investigation of the effects of Micro Pin Fin Arrays (MPFA) on the fuel oxidation efficiency of catalytic combustion is presented in this thesis. Complete combustion of the fuel is essential for operation at maximum efficiency and high standards of environmental cleanliness desired in existing microscale combustion...
