RISConjugate Thermal Analysis of Air-Cooled Discrete Flush-Mounted Heat Sources in a Horizontal Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal analysis with comprehensive treatment of conjugate heat transfer is performed in this study for discrete flush-mounted heat sources in a horizontal channel cooled by air. The numerical ...
Research on the Effect of Whole Cylinder Block on EHL Performance of Main Bearings Considering Crankshaft Deformation for Internal Combustion Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the analyses of elastohydrodynamic lubrication (EHL) of crankshaft bearings considering the deformation of the whole cylinder block and crankshaft under load were carried out for ...
Numerical and Experimental Investigation of Laminar Channel Flow With a Transparent Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical and experimental investigation is undertaken for developing laminar flow in a duct with one opaque, uniformly heated wall and one transparent wall. In the numerical model, mixed ...
Design of a Novel Air Bearing Workbench for Rotary Ultrasonic Drilling of Advanced Ceramics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel air bearing workbench used in rotary ultrasonic drilling of advanced ceramics was designed to constantly and sensitively control the cutting force. Compared with traditional feed systems, ...
Two-Step Mixing Process Elaboration of the Hot-Mix Asphalt Mixture Based on Surface Energy Theory
Publisher: ASCE
Abstract: Hot-mix asphalt (HMA) is a multicomponent mixture composed of asphalt, coarse and fine aggregates, fillers, and other necessary additives. The bitumen–aggregate adhesion and performance of HMA are mainly dependent on such ...
Microscale Property Evaluation of the Interface between Cement Emulsified Asphalt and Aged Asphalt in Emulsified Asphalt Cold Recycled Mixture
Publisher: ASCE
Abstract: To study the microscale properties of the interface between cement emulsified asphalt and aged asphalt in the emulsified asphalt cold recycled mixture, the PeakForce quantitative nano mechanics (PF-QNM) technology of atomic ...
Relationships between Asphalt-Layer Moduli under Vehicular Loading and FWD Loading
Publisher: ASCE
Abstract: The modulus of the asphalt layer in a pavement structure subjected to vehicular loading is different from that subjected to falling weight deflectometer (FWD) loading. A comprehensive approach is developed in this study ...
Investigation of the Influence of Aging on the Nanoscale Adhesion of Asphalt from the Perspective of AFM-IR–Based Chemical Properties
Publisher: ASCE
Abstract: Investigation of the adhesion mechanism during the aging process of the asphalt-aggregate interface from a microscopic point of view contributes to the solution of water damage of asphalt pavements. So far, some work has ...
Estimation of Vehicle Speed from Pavement Stress Responses Using Wireless Sensors
Publisher: ASCE
Abstract: Vehicle speed is a crucial input for mechanistic-based design and maintenance decision making of asphalt pavement. It can be measured using direct methods and indirect methods. Direct methods, such as video camera and ...
Variability Investigation of Reclaimed Asphalt Pavement Materials
Publisher: ASCE
Abstract: The maximum permissible content of reclaimed asphalt pavement (RAP) is restricted due to its negative effect on the stability of hot mix asphalt with RAP (HMA-RAP) performance. To address this problem, characteristics of ...
