A simplified model of heat transfer between large-particle gas-fluidized beds and immersed surfaces

Creator:: Bakke, Paul D.
Abstract:: A simplified model of the combined particle convective and radiative components of heat transfer between large-particle gas-fluidized beds and immersed surfaces was developed. This analytical model was based on the single particle formulation of Adams and Welty [4,9], with the added assumptions of one-dimensional heat conduction in the particle and...

A theoretical study of the radiative contribution to heat transfer between a high-temperature, large-particle gas-fluidized bed and an immersed tube

Creator:: Mahbod, Bahram
Abstract:: An analytical model of the radiative contribution to the total heat transfer between a large-particle (greater than 1 mm) gas-fluidized bed and an immersed horizontal tube is discussed. The model is applied to the case of a bubbling bed and the emulsion phase contribution is obtained from a detailed analysis...

Designing and creating the Oregon State age and disability simulation suit

Creator:: Rahrer, Adam P.
Abstract:: Over 54 million people report having disabilities in the United States. In addition, there are 40.3 million people 65 years and older living in America. As the population continues to live longer and problems with obesity continue to increase, the number of people with limited capabilities will escalate as well....

Model Predictive Control of a Phase Change Process for Wastewater Purification Application

Creator:: Anderson, Kyle S.
Abstract:: In the United States, the oil and gas extraction industry produces large amounts of highly contaminated wastewater that is seldom treated for reuse in other applications. Current wastewater storage and disposal strategies lead to contamination of valuable freshwater resources that can have negative effects on both human communities and the...

Investigating arc behavior in a DC vacuum arc remelting furnace using magnetic flux density measurements

Creator:: Woodside, Rigel
Abstract:: The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...

The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

Creator:: Dimas-Harms, Colton R.
Abstract:: In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...

Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

Creator:: Taie, Zachary
Abstract:: There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

Process Physics, Strategies and Economics in Metal Additive Manufacturing and Digital Microstructural Control for Energy and Chemical Process Components

Creator:: Manoharan, Sriram
Abstract:: Advances in plant construction within the energy and chemical process industries require inexpensive process intensification (PI) technology as a means to reduce plant size for enabling modular construction. One form of PI is microchannel process technology where arrays of microchannels, having hydraulic diameters on the order of 0.1 to 1...

Experimental Investigations of the Unsteady Aerodynamics of Oscillating Airfoils Operating in the Energy Harvesting Regime

Creator:: Siala, Firas F.
Abstract:: The rising global trend to reduce dependence on fossil fuels has provided significant motivation toward the development of alternative energy conversion methods and new technologies to improve their efficiency. Recently, oscillating energy harvesters have shown promise as highly efficient and scalable turbines, which can be implemented in areas where traditional...
