RISA Finite-Differences Derivative-Descent Approach for Estimating Form Error in Precision-Manufactured Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background: Form-error measurement is mandatory for the quality assurance of manufactured parts and plays a critical role in precision engineering. There is now a significant literature on ...
Queuing and Statistical Analysis of Freeway Bottleneck Formation
Publisher: American Society of Civil Engineers
Abstract: A modified approach to treat traffic flow parameters (flow, density, and speed) has been introduced in this paper. A queuing analysis has been conducted on traffic flow data on Interstate 94 in the Minneapolis–St. Paul ...
Pasternak Model for Oblique Pullout of Inextensible Reinforcement
Publisher: American Society of Civil Engineers
Abstract: An analysis is presented for evaluation of the pullout capacity of sheet reinforcement subjected to oblique pullout force considering that the subgrade soil is represented as a two-parameter linear-elastic Pasternak model ...
Effect of Flow Parameter Variations on Full Coverage Film-Cooling Effectiveness for a Gas Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of film-cooling holes placed along the span of a fully cooled high pressure turbine blade in a stationary, linear cascade on film-cooling effectiveness is studied using the pressure ...
Impingement Heat Transfer From Jet Arrays on Turbulated Target Walls at Large Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments to investigate heat transfer and pressure loss from jet array impingement are performed on the target wall at high Reynolds numbers. Reynolds numbers up to 450,000 are tested. The presence of a turbulated target ...
Heat Transfer and Pressure Loss Measurements in a Turbulated High Aspect Ratio Channel With Large Reynolds Number Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments to investigate heat transfer and pressure loss are performed in a rectangular channel with an aspect ratio of 6 at very high Reynolds numbers under compressible flow conditions. Reynolds numbers up to 1.3 أ— 106 ...
Constitutive Modeling Including Creep- and Rate-Dependent Behavior and Testing of Glacial Tills for Prediction of Motion of Glaciers
Publisher: American Society of Civil Engineers
Abstract: The disturbed state concept (DSC) is used to characterize the deformation behavior of glacial tills, which may have a significant role in the motion of overlying glaciers with attendant implications for global climate ...
Nonlinear Analysis of Shape Memory Devices With Duffing and Quadratic Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigate the linear and nonlinear response of shape memory alloy (SMA)-based Duffing and quadratic oscillator under large deflection conditions. In this study, we first present thermomechanical ...
An Ontology-Based Framework for Decision Support in Assembly Variant Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The designer generates a variant product by applying several design suggestions that fulfilled a variety of customer requirements. These design suggestions rely on multiple domains of expert knowledge, which are unstructured ...
Numerical Investigation of a Confined Laminar Jet Impingement Cooling of Heat Sources Using Nanofluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermal and fluid dynamic behavior of a confined two-dimensional steady laminar nanofluid jet impinging on a horizontal plate embedded with five discrete heating elements subjected to a constant surface heat flux has ...
