Numerical study on engineering aspect of the cell geometries and flow channel design of Vanadium redox flow battery (V-RFB)

This thesis presents the hydrodynamics behavior of the Vanadium redox flow battery (V-RFB) by using 3D computational fluid dynamics (CFD) models to study the pump power (pump energy consumption) and electrolyte flow distribution required within the cell. Pumping power and uniformity electrolyte flow...
