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...

Comparison of R404A condensation heat transfer and pressure drop with low global warming potential replacement candidates R448A and R452A

Creator:: Jacob, Tabeel A., Matty, Ethan P., and Fronk, Brian M.
Abstract:: The objective of this paper was to measure and compare the heat transfer coefficient and pressure drop of R404A and two potential replacement candidate refrigerants with a lower global warming potential, R448A and R452A. Experiments were conducted inside a 4.7 mm horizontal tube at mass fluxes ranging from 100 to...

New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

Creator:: Senogles, Andrew
Abstract:: Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...

A Literature-based Dataset Containing Statistical Compositions and Reactivities of Commercial and Novel Supplementary Cementitious Materials

Creator:: Bharadwaj, Keshav, Isgor, O. Burkan, and Weiss, W. Jason
Abstract:: This dataset contains the chemical composition and reactivities of commercially used SCMs such as silica fume, Class-F and Class-C fly ashes, slags, and calcined clays. The dataset also includes the chemical composition and reactivity (where available) for several SCMs that are currently not specified in standard specifications by ASTM or...

Evaluating the Feasibility of Mass Timber as a Mainstream Building Material in the US Construction Market: Industry Perception, Cost Competitiveness, and Environmental Performance Analysis

Creator:: Ahmed, Shafayet
Abstract:: Mass timber has been considered as a promising building material because of its structural rigidity, environmental sustainability, and renewability nature. In Europe and Australia, mass timber materials have been used for many different types of construction such as residential, commercial, education, and industrial. However, the construction practitioners in the U.S....

Beach Dune Subsurface Hydrodynamics and the Formation of Dune Scarps

Creator:: Bond, Hailey G.
Abstract:: The formation of beach scarps is a challenging morphodynamic phenomenon that the coastal community has yet to capture in coastal change models. Understanding scarp formation is crucial to accurately predicting coastal erosion and vulnerability during extreme events, as models without parameters for scarp formation and development severely underpredict total erosion...

Seismic performance and collapse assessments of reinforced concrete lateral- force resisting systems

Creator:: Buniya, Mustafa Kamil
Abstract:: Nonlinear response history analysis (NRHA) is increasingly becoming more accessible and prevalent in research and practice. As the accuracy of the NRHA results depends on the ground motion characteristics and the robustness of the numerical model, research has focused on the development of guidance for performance-based seismic design and assessment...

Post-wildfire Investigation of Civil Infrastructure Following the 2018 Camp Fire

Creator:: Schulze, Stefanie S.
Abstract:: Wildland-urban interface (WUI) communities, where forested land boundaries or intermixes with infrastructure, are quickly growing in the US. WUI communities have grown substantially from 1990 to 2010, with an increase of 12.7 million houses and 25 million people. Wildfires encroaching on WUI communities can cause damage to both above ground...

Coastal Soil and Structure Behavior during Earthquake-Tsunami Multi-Hazards

Creator:: Qiu, Yingqing
Abstract:: Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...

Data Assimilation using Synthetic-Aperture Radar Imagery for Bathymetry Inversion at the Mouth of the Columbia River

Creator:: Harper, Spencer H.
Abstract:: Synthetic-aperture radar (SAR) imagery can provide wavenumber and frequency data to generate bathymetry estimates for locations where limited access or extreme ocean conditions can make standard bathymetry survey techniques difficult or impossible. The availability of SAR data could allow for regular bathymetry estimates of navigational channels providing insight into dredging...
