Efficient Poisson’s Ratio Evaluation of Weft-Knitted Auxetic Metamaterials

open access: yesTextiles, 2023
Auxetic metamaterials expand transversely when stretched longitudinally or contract transversely when compressed, resulting in a negative Poisson’s ratio (NPR).

Hydrodynamic Lubrication Effects of Multiple Circular Bump Pattern for a Thrust Sliding Bearing of a Scroll Compressor

open access: yesTribology Online, 2012
The optimum texturing pattern for a thrust sliding bearing of a scroll compressor was investigated. As the basis of lubrication analysis for multiple circular bumps pattern, fundamental hydrodynamic lubrication effects of the axisymmetric circular ...

The effect of misalignment on the performance of tilting pad thrust bearing with TEHD coupling model and turbulence model

open access: yesAdvances in Mechanical Engineering, 2023
A thermoelastohydrodynamic (TEHD) coupling model is developed to study the static performance of a heavy-duty tilting pad thrust bearing (TPTB) under the effect of axis misalignment.

Computational fluid dynamics model for a variable conductance thermosyphon

open access: yesCase Studies in Thermal Engineering, 2021
A variable conductance thermosyphon is a unique type of heat pipe that responds passively to changes in thermal environment because of the presence of non-condensable gas (NCG).

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
