A novel multiscale flow battery simulation approach is presented. Therefore, the mass transfer coefficient (MTC) extracted from 3D-resolved microscale simulations, transferred to homogenized cell scale and compared empirical formulations literature. The models are parameterized with an organic system experimentally validated on microscale. It resolves real geometry of electrode microstructure o...

Heat transfer coefficients were measured in a circular tube with dimpled surface. The almond type dimples were fabricated, the tube diameter (D) 19mm and dimple depth 3 mm ratio was kept constant, while holding diameter 10mm of dimple is required length 21.5mm because of the elongated shape. The Reynolds number based on the channel hydraulic diameter was varied from 25000to 95000. An experiment...

The impact of bioreactor and sparger scale-up on gas transfer properties was investigated using four geometrically similar bioreactors ranging in size from 15-L to 2500-L total volume with the same sintered metal frit (microporous) sparger design. The mass transfer coefficients for both oxygen and carbon dioxide were measured at each scale at various flow rates. Scale did not directly affect ga...
