A study on lubrication characteristics of contaminated oil film and abrasive wear in fuel gear pumps based on discrete element method

Aviation fuel gear pumps are prone to accelerated wear of friction pairs during long-term high-load operation, generating metallic particles that contaminate the sliding bearing oil film and trigger abrasive wear. To address this, a coupling solution of the discrete element method (DEM) with a two-phase flow lubricat...

Hybrid Uncertainty Sensitivity Analysis Based on the HSIC for High-Dimensional Responses with Aleatory-Epistemic Separation

Quantifying the influence of hybrid aleatory and epistemic uncertainties on high-dimensional system responses remains a major challenge in global sensitivity analysis (GSA). Existing Hilbert--Schmidt Independence Criterion (HSIC)-based approaches are primarily restricted to single-output settings and lack a rigorous de...
