RIST-Maps-Based Tolerance Analysis of Composites Assembly Involving Compensation Strategies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Clamping force and shimming are two important compensation processes in the composite assembly. Their effects on variation propagation should be investigated in tolerance analysis. The paper presents a tolerance analysis ...
Condensation in Microchannels: Detailed Comparisons of Annular Laminar Flow Theory With Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A relatively simple theory of annular laminar film condensation in microchannels, based on the Nusselt approximations for the condensate film and a theoretically based approximation for the vapor shear stress, has no ...
A Clustering-Based Framework for Performance Degradation Prediction of Slewing Bearing Using Multiple Physical Signals
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Diagnosing the failure or predicting the performance state of low-speed and heavy-load slewing bearings is a practical and effective method to reduce unexpected stoppage or optimize the maintenances. Many literatures focus ...
A Multi-Objective Comprehensive Evaluation of Heat Transfer Performance of a Direct-Contact Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Direct-contact heat exchangers have great potential for waste-heat utilization. This study established a multi-objective evaluation model of the volumetric heat-transfer coefficient, entransy dissipation, and uniformity ...
Effects of Vapor Velocity and Pressure on Marangoni Condensation of Steam Ethanol Mixtures on a Horizontal Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Careful heattransfer measurements have been conducted for condensation of steamethanol mixtures flowing vertically downward over a horizontal, watercooled tube at pressures ranging from around atmospheric down to 14 kPa. ...
Pressure Drop During Condensation in Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper reports calculations of friction pressure gradient for the special case of laminar annular flow condensation in microchannels. This is the only flow regime permitting theoretical solution without having recourse ...
Apparent Emissivity of Combustion Soot Aggregate Coating at High Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Soot aggregates frequently occur during combustion or pyrolysis of fuels. The radiative properties of soot aggregates at high temperature are important for understanding soot characteristics and evaluating heat transfer ...

Atmospheric Duct Detection Using Wind Profiler Radar and RASS
Publisher: American Meteorological Society
Abstract: AbstractA method of detecting atmospheric ducts using a wind profiler radar (WPR) and a radio acoustic sounding system (RASS) is proposed. The method uses the RASS to measure the virtual temperature profile and calculate ...
