Stability of a Rotor Partially Filled With Fluid: Test Facility and Experimental Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid trapped in a hollow, rotating component may lead to subsynchronous vibrations, resulting in high vibration amplitudes. This asynchronous response is observed around 0.55–0.92× after passing through the first critical ...
Bubble Dynamics and Heat Transfer Characteristics of Flow Boiling in a Single Pentagonal Rib Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase flow boiling is the preferred method for efficient heat dissipation in electronic equipment, so the bubble dynamics and heat transfer characteristics of flow boiling in a single pentagonal rib channel are numerically ...
Design Optimization, Thermohydraulic, and Enviro-Economic Analysis of Twisted Perforated Tape Insert-Based Heat Exchanger With Nanofluid Using Computational Fluid Dynamics and Taguchi Grey Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effect of perforated twisted tape insert (PTTI)-based heat exchanger (HX) utilizing nanofluid as working fluid undercooling, turbulent flow model has been investigated numerically. Parameters, i.e., ...
Modeling and Design of Hinged Tile-Based Curling Air Surface for Morphing Windshield Cowling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gap between the windshield and hood allows windshield wipers to operate, but causes problems gathering leaves and snow. Active morphing approaches provide an opportunity to create a windshield cowling that addresses ...
Accelerated Deterministic Phonon Transport With Consistent Material Temperature and Intensities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a method for deterministically solving the frequency and temperature dependent phonon radiative transport (PRT) equation in the single-mode relaxation time (SMRT) approximation in the self-adjoint angular flux ...

Mapping the Chaotic Transitions of the Lorenz Equations With Unsupervised Machine Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prior work has explored utilizing machine learning for the Lorenz system in the time domain. In this work, we have focused on applications of machine learning for predicting the onset of chaotic transitions in the Lorenz ...
Performance Analysis of Central Processing Unit Heat Sinks Fitted With Perforation Technique and Splitter Inserts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The increase in the heat dissipation rate in heat sinks (HSs), the reduction of the occupied volume and mass, and the elimination of the lower heat transfer areas (LHTAs) behind the pins are the main parameters to be ...
A Switched Dynamical System Approach to the Flow and Heat Transfer of Immiscible Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides important insights into immiscible fluids models, which can exhibit complex nonlinear behavior due to variations in thickness, viscosity, thermal conductivity, and jump velocity fields across the interface ...
