A structured and unstructured quadrilateral grid was generated, containing 10441 elements.
It illustrated the laws of a dilute regime at the bottom and a dense regime at the top, but didn’t show the core-annulus structure because of the lower solid volume fraction in region 3.

There are wide application in the fields of physics, chemistry and biology.
The nutrient substrate is absorbed into the cell and then transfers to structure energy to support cells growth.
The degradation kinetics can be represented through the following differential equations: (1) (2) (3) where CL ,CM and CR represent concentrations of nutrient substrate (L), microorganism structure energy (M) and metabolites energy (R), respectively, mmol/L; α is ratio between maximum specific absorption rate and half-saturation constant; YML is growth efficiency; yRM represents stoichiometric yield constants of M/R; jM are maintenance flux from structural mass.
