Gas Bubbles Expansion and Physical Dependences in Aluminum Electrolysis Cell: From Micro- to Macroscales Using Lattice Boltzmann Method

Figure 1

Schematic expansion of gas divided into five regimes. Phase (0) depicts the thermal expansion of the precursor, phase (I) denotes the bubbles nucleation and expansion under surface of anodes, the expansion in the semisolid and liquid range is in phase (II), phase (III) is the expansion in the liquid temperature range, and finally phase (IV) is the gas bubbles collapse.
