RISEffect of Particle Concentration on Shape Deformation and Secondary Atomization Characteristics of a Burning Nanotitania Dispersion Droplet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Secondary atomization characteristics of burning bicomponent (ethanol–water) droplets containing titania nanoparticles (NPs) in dilute (0.5% and 1 wt.%) and dense concentrations (5% and 7.5 wt.%) are studied experimentally ...
Monitoring the Degradation in the Switching Behavior of a Hydraulic Valve Using Recurrence Quantification Analysis and Fractal Dimensions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Valves are crucial components of a hydraulic system that enable reliable fluid management. Hydraulic valves actuated by a solenoid are prone to degradation in their switching behavior, which may induce undesirable fluctuations ...
System Level Analysis of Acoustically Forced Nonpremixed Swirling Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an experimental investigation of dynamic response of nonpremixed atmospheric swirling flames subjected to external, longitudinal acoustic excitation. Acoustic perturbations of varying frequencies ...
Internal Leakage Detection in Hydraulic Pump Using ModelAgnostic Feature Ranking and Ensemble Classifiers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic pumps are key drivers of fluid powerbased machines and demand high reliability during operation. Internal leakage is a key performance deteriorating fault that reduces pump’s efficiency and limits its predictability ...
Pressure Signal-Based Analysis of Anomalies in Switching Behavior of a Two-Way Directional Control Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solenoid operated direction control valves, responsible for regulating the flow of fluid in hydraulic circuit highly relies on the control current for their actuation. The control currents supplied to the solenoid generate ...
Performance Prediction of an Axial Piston Pump With Increasing Severity of Leakage Fault in Single and Multiple Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As axial piston pumps (APP) become increasingly compact to meet the size, weight, and performance demands (high pressure ratings), they are prone to wear, and hence the leakage between the sliding parts, which run under ...
Fuzzy Recurrence Plots for Shallow Learning-Based Blockage Detection in a Centrifugal Pump Using Pre-Trained Image Recognition Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rags, dusts, foreign particles, etc., are the primary cause of blockage in the centrifugal pump and deteriorate the performance. This study elaborates an experimental and data-driven methodology to identify suction, ...
Internal Leakage Detection in Hydraulic Pump Using Model-Agnostic Feature Ranking and Ensemble Classifiers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic pumps are key drivers of fluid power-based machines and demand high reliability during operation. Internal leakage is a key performance deteriorating fault that reduces pump’s efficiency and limits its predictability ...
Semi-Supervised Approach Using Transductive Support Vector Machine for Internal Leakage Detection in Two-Stage Hydraulic Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic cylinders with higher stages of extraction are extensively used in earthmoving and heavy machines due to their longer stroke, shorter retracted length, and high-end performance. The rigorous and long hours of ...
Response Dynamics of Recirculation Structures in Coaxial Nonpremixed Swirl Stabilized Flames Subjected to Acoustic Forcing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the timemean and phaselocked response of nonreacting as well as reacting flow field in a coaxial swirling jet/flame (nonpremixed). Two distinct swirl intensities plus two different central pipe flow rates ...
