Title:
LES of anaerobic digester mixing using the Actuator Line Model
Abstract:
The mixing of wastewater sludge inside a stirred anaerobic digestion tank with a height and diameter of 15.7 m is simulated using Large-Eddy-Simulation and the finite-volume multigrid coupled solver MGLET. The mixing propeller is modelled as an actuator disc and line that adds a constant momentum to the right hand side of the momentum equations to generate an axial downward flow of approximately 20 m^3 s^-1 through the propeller swept area. Anaerobic digestion sludge is treated as a single-phase...     »
