RISFinding the Shortest Path on a Polyhedral Surface and Its Application to Quality Assurance of Electric Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a computational method for finding the shortest path along polyhedral surfaces. This method is useful for verifying that there is a sufficient distance between two electrical ...
Finite Element Simulation of the Tightening Process of Bolted Joint With a Bolt Heater
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tightening operation with a bolt heater has advantages surpassing those of other tightening methods. Currently, a bolt heater is mainly applied to tighten huge bolts that cannot be clamped ...
A Numerical and Experimental Investigation of Low-conductivity Unglazed, Transpired Solar Air Heaters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of low-conductivity unglazed, transpired solar collectors was determined numerically and experimentally. The numerical work consisted of modeling flow conditions, plate geometries, ...
A Strain-Based Formulation for the Coupled Viscoelastic/Damage Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A strain-based thermodynamics framework is proposed for modeling the continuum damage behavior of viscoelastic materials. Damage is represented by an internal state variable in the form of a ...
An Overset Finite-Element Large-Eddy Simulation Method With Applications to Turbomachinery and Aeroacoustics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical method for the prediction of an unsteady fluid flow in a complex geometry that involves moving boundary interfaces is presented in this paper. The method is also applicable to the ...
Inability of Free-Interface Modes in Representing Stress Resultants Near the Free Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the fundamental cause of the slow convergence of a direct free-interface component mode synthesis method, we point out the inability of free-interface normal modes in representing the stress ...
High Pressure Annular Two-Phase Flow in a Narrow Duct: Part I—Local Measurements in the Droplet Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed measurements have been made in a high pressure, adiabatic (boiled at the inlet) annular flow in a narrow, high aspect ratio duct using a gamma densitometer, hot-film anemometer and ...
High Pressure Annular Two-Phase Flow in a Narrow Duct: Part II—Three-Field Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper outlines the development of a three-field modeling approach in annular flow and the predictive capability of an analysis code. Models have been developed here or adapted from the ...
