Numerical Simulation of a Novel Flow Channel with Aligned Concave-Convex Cavities to Enhance the Performance of PEMFC

چکیده
Abstract The bipolar plates are important components of fuel cells and its characteristics cross-section shape have a significant influence on the performance PEMFCs. A new-type flow channel with aligned fan-shape concave-convex cavities is presented. 3D, single-phase model for PEMFC developed. polarization curve, current density distribution as well oxygen concentration straight compared through CFD simulation. has been more improved than that channels. simulation results also show fan-shaped improves net power increased by 2.6%. Moreover, proposed novel very simple inexpensive manufacturing.

15 صفحه اولwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
15 صفحه اولNumerical simulation of Laminar Free Convection Heat Transfer around Isothermal Concave and Convex Body Shapes
In the present research, free convection heat transfer from isothermal concave and convex body shapes is studied numerically. The body shapes investigated here, are bi-sphere, cylinder, prolate and cylinder with hemispherical ends; besides, they have the same height over width (H/D = 2). A Numerical simulation is implemented to obtain heat transfer and fluid flow from all of the geometries in a...
