RISComparison of Convective and Radiative Heating Modes on the Thermophysical Changes of a Cerium Nitrate Droplet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we try to establish the equivalence or similarity in the thermal and physiochemical changes in precursor droplets (cerium nitrate) in convective and radiative fields. The radiative field is created through ...
Effect of Particle Concentration on Shape Deformation and Secondary Atomization Characteristics of a Burning Nanotitania Dispersion Droplet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Secondary atomization characteristics of burning bicomponent (ethanol–water) droplets containing titania nanoparticles (NPs) in dilute (0.5% and 1 wt.%) and dense concentrations (5% and 7.5 wt.%) are studied experimentally ...
Strut-Relieved Single Steel Haunch Bracing System for Mitigating Seismic Damage of Gravity Load Designed Structures
Publisher: American Society of Civil Engineers
Abstract: A large number of existing reinforced concrete structures, constructed before the 197s, are poorly designed and inadequately detailed. The design and detailing of these structures are based on the prevailing guidelines and ...
Design of Tuned Mass Damper Fluid Inerter for Wind-Induced Vibration Control of a Tall Building
Publisher: ASCE
Abstract: In this paper, the problem of wind-induced vibration in tall buildings is addressed by utilizing a new type of damper, the tuned mass damper fluid inerter (TMDFI). The TMDFI incorporates an inerter in the classical tuned ...
Early Detection and Monitoring of Corrosion in Reinforced Concrete Structures Using Coupled Time-Frequency Analysis
Publisher: American Society of Civil Engineers
Abstract: Corrosion of steel rebar in reinforced concrete (RC) constructions is an issue of great concern toward ensuring the integrity of civil structures, and thus, detection of the on-set of corrosion process, if any, will ...
Virtual Frequency Fusion Technique: Detecting Multiple Damages via Broadband Lamb Wave Field Using Scanning Laser Vibrometry
Publisher: American Society of Civil Engineers
Abstract: This article presents an efficient frequency fusion method by virtual acquisition of multifrequency guided wave velocity data for robust and accurate localization of multiple damages in plate-like structures. Lamb waves ...
Performance Evaluation of a Stone Masonry–Arch Railway Bridge under Increased Axle Loads
Publisher: American Society of Civil Engineers
Abstract: Many of the masonry arch bridges in the network of railway bridge stock belong to the civil engineering heritage of the railways. Therefore, their maintenance and management require careful consideration. An effective ...
Modeling of Thermophysical Processes in Liquid Ceramic Precursor Droplets Heated by Monochromatic Irradiation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A transient heat and mass transfer model is formulated to describe radiative heating of ceramic precursor droplets in a nonconvective environment. Heating causes vaporization of solvent from the ...
System Level Analysis of Acoustically Forced Nonpremixed Swirling Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an experimental investigation of dynamic response of nonpremixed atmospheric swirling flames subjected to external, longitudinal acoustic excitation. Acoustic perturbations of varying frequencies ...
Experimental Analysis of Water Vapor Diffusion Through Porous Membranes in a Proton Exchange Membrane Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report the diffusion characteristics of water vapor through two different porous media, viz., membrane electrode assembly (MEA) and gas diffusion layer (GDL) in a nonoperational fuel cell. Tunable diode laser absorption ...
