文摘
- •
Multiphysics numerical analysis has been performed for advanced metallic BP design.
- •
A structural model was developed to predict the mechanical variation of GDM.
- •
Flow patterns were analyzed using the entropy generation theory in an open system.
- •
A higher channel-to-rib width results in greater volumetric deformation of GDM.
- •
Higher flow resistance along the channel drives larger bypass flow through GDM.
