RISStatus of Enhanced Heat Transfer in Systems With Natural Refrigerants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Global environmental and energy concerns have prompted the heating, ventilating, air-conditioning, and refrigeration industry to revisit the use of natural refrigerants. Nearly all natural refrigerants ...
Sensitivity of Oklahoma Binders on Dynamic Modulus of Asphalt Mixes and Distress Functions
Publisher: American Society of Civil Engineers
Abstract: For designing pavements many state agencies, including those in Oklahoma, use the 1993 AASHTO Guide for Design of Pavement Structures, which is empirical in nature. However, the Mechanistic-Empirical Pavement Design Guide ...
Noise Reduction of Ceiling Fans in Mass Production Applying DMAIC-Six Sigma Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Success and business reputation depend upon the quality of products where product quality relies on the capability of a process, yield value, sigma score, etc. The poor quality of ceiling fans was determined from the Pareto ...
Forensic Evaluation of Premature Pavement Failures in Arkansas
Publisher: American Society of Civil Engineers
Abstract: As part of a major rehabilitation program in 1999–24, several sections of the Arkansas interstate system were overlaid. Some of these sections experienced severe distresses (rutting and cracking), but the others performed ...
Forensic Investigation of Ten Asphalt Interstate Pavements with Varying Performance in Arkansas
Publisher: American Society of Civil Engineers
Abstract: After 9–12 years of service, multiple sections of various interstates within Arkansas prematurely deteriorated. Four of these “poor” performing sections were compared to two “medium” and four “good” performing sections ...
Economic and Performance Evaluation of Heat Sink Options in Combined Cycle Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is a guideline to selecting the most appropriate technology for the power plant heat sink based on water availability, site location, and wastewater disposal requirements. The paper ...
Influence of Soil Moisture on Urban Microclimate and Surface-Layer Meteorology in Oklahoma City
Publisher: American Meteorological Society
Abstract: he influence of soil moisture on the surface-layer atmosphere is examined in this paper by analyzing the outputs of model simulations for different initial soil moisture configurations, with particular emphasis on urban ...
Effects of Aging and Rejuvenation on Surface-Free Energy Measurements and Adhesion of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a study that was conducted to understand the impacts of aging and rejuvenation on fundamental properties of asphalt binders. A Performance Grade (PG) 64-22 binder was aged to simulate the ...
A Modified Correlation for Flow Boiling Heat Transfer in Plate Heat Exchangers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Corrugated plate heat exchangers are increasingly used in two-phase flow applications for their flexible compact size and efficient heat transfer performance. This paper presents a brief review of recent studies on the ...
Impact of Nanoclays on Chemical Fractions and Mechanical Performance of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Asphalt binder often is modified to obtain better performance of the pavement. Some recent studies have considered nanoclay as an alternative to currently practiced styrene-butadiene-styrene (SBS) modification to reduce ...
