Title: Normal temperature analogue experiment of anode bubble's behavior in aluminum electrolysis cells
Abstract: A electrolysis experiment using the bluestone solution as electrolyte and graphite as anode was carried out to simulate and research the anode gas's law of movement and its influence to the electrolyte flow.When the gradient of anode is below 6°,the change of it has significant influence to the bubble's velocity.The increase of the gradient will speed the bubble's velocity but decrease the bubble's size.When the gradient of anode is above 6°,the phenomenon of bubbles' combination hardly exists,and the change of the anode's gradient has little influence on the bubble's velocity.The bubbles' impetus function to the electrolyte flow mainly lies in the thin layer of anode bottom where the bubbles are.There are back-flow phenomena in the bottom layer of electrolyte,but the velocity of electrolyte is very small,and the velocity is about 5mm/s.
