An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Computational Modeling of Smoldering Combustion in Wildland Fuels

Creator:: Jayasuriya, Waduge Jayani A.
Abstract:: Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

Design of 3D-Printed Soft Pneunet Actuator for Robotic Fruit Harvesting

Creator:: Wilhelm, Lissette J. H.
Abstract:: This work details the development of 3D printed TPU pneunet actuators for use in apple picking for agricultural soft robotics. These actuators increase the force capabilities of soft pneunets and simplify manufacturing. Grippers based on these actuators are ideal for apple picking because they are compliant, yet exert sufficient force...

Experimental Study of the Impact of Physical and Chemical Properties on Smoldering Combustion in Natural Fuels

Creator:: Smucker, Benjamin
Abstract:: Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...

Design and Testing of the FUEL System: Integrating Engineering and Ethnographic Methods in Global Development Efforts

Creator:: Ventrella, Jennifer L.
Abstract:: Clean cooking technologies and fuels have been cited as a viable way to slow climate change and reduce the health and environmental impacts associated with traditional cooking devices used by 40% of the world. While engineers in the Design for Development sector have created hundreds of stove designs that perform...

Soot Modeling: GPU Accelerated Direct Simulation Monte Carlo

Creator:: Lorson, Paige
Abstract:: For this project, we designed a soot modeling software to produce a full particle density function. This model uses the Direct Simulation Monte Carlo with a full conditioning particle selection method to capture soot nucleation and coagulation in a diffusion flame. We investigate the use of graphic processing units as...

Simulating Soot Formation and Growth using a Parallel Coupled Monte Carlo Method

Creator:: Peters, Jordan
Abstract:: Small hydrocarbon particles such as soot and soot precursors pose a serious threat to human health and Earth's climate. Understanding the mechanisms by which soot particles form and grow is the first step to reducing the prevalence of these particles. Computational simulations are used to investigate combusting systems which are...

Ignition of Fuel Beds by Firebrands

Creator:: Bean, Derek R.
Abstract:: The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

Creator:: Strahl, Jordan D.
Abstract:: The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....
