Journal ArticleDOI

A robust and efficient stepwise regression method for building sparse polynomial chaos expansions

TL;DR: The results show that the developed sparse regression technique is able to identify the most significant PC contributions describing the problem and the most important stochastic features are captured at a reduced computational cost compared to the LAR method.
Journal ArticleDOI

Numerical study of electroosmotic micromixing of non-Newtonian fluids

TL;DR: In this article, a numerical investigation of flow of power-law fluid in a two-dimensional microchannel with nonuniform zeta potential distributions along the channel walls was carried out via finite volume scheme.
Journal ArticleDOI

Numerical analysis of mixed electroosmotic/pressure driven flow of power-law fluids in microchannels and micropumps

TL;DR: In this paper, the effects of the fluid behavior index (n, zeta potential and electric double layer (EDL) thickness) on characteristics of pure EO and mixed EO/PD flow of power-law fluids in microchannels and micropumps were investigated.
Journal ArticleDOI

Unsteady pressure measurements on the runner of a Kaplan turbine during load acceptance and load rejection

TL;DR: In this paper, the authors investigated the effect of the transients on the turbine performance and the formation and mitigation processes for the rotating vortex ropes and their effects on the forces exerted on the runner.
