Although various highly active transition metal-based electrocatalysts have been identified for the anodic oxygen evolution reaction (OER) alkaline water electrolysis, necessity of a binder to coat onto conductive supports affects overall durability. Thus, developing active, durable, and binder-free anode is beneficial advancing electrolysis broader applications. This study presents new yet effective surface sulfidation method converting commercial FeNiCo alloy, Kovar, into stable, OER...
Unsteady Reynolds-Averaged Navier-Stokes (URANS) simulation has been conducted to investigate how flow coefficient affects unsteady impeller loading. Simulations have carried out at three coefficients — near stall, design, and choke conditions for a radial gap of 1.04. For computational efficiency, the two diffuser passages via Fourier Transformation method. Both steady simulations validated against experimental data. The loading (the difference between maximum minimum loadings) is largest...
