Prognostics and Maintenance Decision-making for Mechanical Systems based on Condition Monitoring Data
DownloadSpring 2024
Condition-based maintenance (CBM) is a maintenance approach that uses condition monitoring data to make maintenance decisions. The goal of CBM is to avoid machine shutdowns, reduce maintenance costs, and improve system safety. In modern mechanical systems, a wide range of sensors are used to...

Characterization of Water Transport and Liquid Accumulation in Proton Exchange Membrane Fuel Cells
DownloadSpring 2024
Hydrogen proton exchange membrane fuel cell (PEMFC) vehicles present a viable solution for decarbonizing the heavy-duty and long-distance transportation sector. They convert the chemical energy of hydrogen directly into electricity, with the only by-products being heat and water and, therefore,...

Predicting polymer drag reduction from polymer solution rheology can be potentially achieved by developing a model between friction factor and rheological characteristics. The model’s foundation depends on establishing a correlation between these parameters, and its robustness depends on the size...
