Sentence examples for flow crossover from inspiring English sources
The effect of gas diffusion layer (GDL) deformation on the flow crossover due to the compression in a fuel cell assembly process is particularly investigated.
A three-dimensional PEM fuel cell numerical model is developed in the aforementioned deformed domain to study the flow crossover between the adjacent channels in the presence of the GDL intrusion.
A parametric study is conducted to quantitatively investigate the effect of the GDL's transport related parameters such as porosity and permeability on the flow crossover between the adjacent flow channels.
The focus of this paper is to study the flow crossover between two adjacent flow channels in a proton exchange membrane (PEM) fuel cell with serpentine flow field design in bipolar plates.
For bacteria captured from gentle flow, a crossover from multivalent to univalent binding is demonstrated as the Debye length is increased from 1 to 4 nm.
Thus, the model was used as a tool to investigate anodic overpotentials, water and methanol crossover flow rates, current density distribution at the catalyst layer/membrane interface, understanding the relationship between flow fields and cell performance.
