Abstract At present, there is no method to accurately characterize the liquid film thickness of shale nanopores with different mineral compositions. This article describes the wetting modification of a 500nm homogeneous quartz model, measures the liquid film thickness under different pressure gradients, and establishes experimental expressions. Based on the experimental results, a prediction meth…

Abstract Background In this study, the relationship between the arrangement of centrally located elliptical holes on Functional Graded Plates (FGPs) and their free vibration behavior was analyzed using the finite element method, while the performance of the hybrid GWMTR algorithm for multivariate regression problems was also evaluated. In the vibration analysis, the effects of material index, hol…
