... variables, number of droplets ( N drops ) , water droplets occupation (WDO), and the Sauter mean diameter (SMD). WDO is the fraction of the GDL surface under the open channel covered by the droplets, while SMD is calculated as the ratio between the sum of volumes and the sum of surface...

...Yong-Sheen Hwang; Suk-Won Cha; Hoon Choi; Dae-Young Lee; Seo Young Kim We investigated the optimum flow channel design for direct methanol fuel cells (DMFCs). Especially, we explored the effect of the pressure drop across the inlet and outlet on the performance of the DMFCs with various flow...

..., makes the subject of the droplet deformation and motion an attractive problem. In this work, we numerically simulate the deformation of a drop of water attached to the wall of a channel flow using full two-dimensional Navier–Stokes equation and the volume-of-fluid method for capturing the interface...
