Probabilistic Wind Power Forecasting for Hybrid Systems

Creator:: Irmas, Cameron
Abstract:: Wind power forecasting provides valuable insights for demand response, energy market operation, and plant control optimization. Probabilistic approaches—which capture uncertainty in these complex systems by representing predictions as probability distributions—represent a growing area of research in wind energy science. However, their applications for wind-based hybrid systems, particularly those focused on...

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...

Early Design Evaluation of See-Through Automotive A-pillar Concepts Using Digital Human Modeling and Mixed Reality Techniques

Creator:: Srinivasan, Sriram
Abstract:: Pillars in modern vehicles provide structural integrity by surrounding the windows and joining the roof with the frame. Although they protect the driver and passengers, A-pillars also create obstruction zones by limiting drivers' forward field of view leading to unforeseeable accidents or mishaps. We argue that providing a better pillar...

Design for Clean Technology Adoption: Application of Discrete Choice Analysis and the Theory of Planned Behavior for Development Engineering

Creator:: Pakravan, Mohammad H.
Abstract:: Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...

In-Tube condensation of zeotropic refrigerant R454C from superheated vapor to subcooled liquid

Creator:: Jacob, Tabeel A. and Fronk, Brian M.
Abstract:: This article investigates the in-tube, superheated, saturated, and subcooled condensation of zeotropic refrigerant mixture R454C. R454C is proposed to replace R404A for commercial refrigeration applications. Quasi-local heat transfer coefficients were measured in a 4.7 mm horizontal tube at mass fluxes ranging from 100 to 500 kg m−2 s−1 at three different saturation...

Care Team Burnout in Human and Veterinary Medicine

Creator:: Alshaiji, Rawan
Abstract:: Medical professionals experience higher rates of burnout than other professions due to the highly stressful nature of their environment. In 2018, 94 percent of physicians reported experiencing burnout – characterized by emotional fatigue, and feelings of depersonalization and low personal accomplishment – at some point in their careers. As emotional...

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...

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...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...

Two-phase flow regimes of condensing R-134a at low mass flux in rectangular microchannels

Creator:: Vanderputten, Michael A., Jacob, Tabeel A., Sattar, Maria, Ali, Nouman, and Fronk, Brian M.
Abstract:: Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...
