A computational fluid dynamic-based method for analyzing the nonlinear relationship between windage loss and pressure in a geotechnical centrifuge

SN Applied Sciences, 2021
Temperature control is an important limitation to further increase in geotechnical centrifuge power. Although vacuum pumps can reduce windage loss, they also negatively affect heat transfer performance.

Failure mechanisms of a spudcan penetrating next to an existing footprint

Theoretical and Applied Mechanics Letters, 2015
Reinstallation of mobile jack-up rigs next to existing footprints is a problematic operation because the spudcan located near the footprints is subjected to eccentric and/or inclined loading conditions. Geotechnical centrifuge studies have measured these
