In this case, a Computational Fluid Dynamics (CFD) analysis has been performed, producing detailed results for the flow field around the pillar, the temperature distribution and the cooling power.
A preliminary, yet not comprehensive, experimental test at low current density without liquid water in PEM fuel cells has found better performance when small sized 3D current collecting pillars and optimal distribution are adopted in a flow field.
Nanopillars were formed in all conditions, and a relatively uniform distribution of pillar diameter and inter-pillar spacing was obtained when the film was annealed at 120 °C (Fig. 3e, f).
This approach can be used to guide both the development and implementation of targeted AES and the objective distribution of Pillar 2 funds between and within Member States.
Our simulations show that, at moderate and high porosities, clustering of the pillars and their spatial distribution do not have a significant effect on the adsorption isotherms.
According to the field conditions, the stress distribution in coal pillar was quantified, and the surrounding rock deformation feature studied with different widths of the pillars in gob-side entry driving.
In this paper we show the calculation of a panel failure probability density function from a statistical distribution of the pillar geometrical attributes reflecting mine design uncertainties and environmental degradation with time.
Because of coal pillar width influence, trended vertical stress distribution is from "v shape" to "partial saddle shape"; tendency vertical stress distribution is "flat disc shape".
Although there have been occasional mine collapses in this region in recent years, all are thought to have involved abandoned mines, most of them worked as much as a century ago without the balanced distribution of support pillars found in today's underground industrial parks.
