Abstract The household batch reactor using cow manure as the substrate generates methane gas used as fuel. This paper presents two-dimensional (3D)
axisymmetric using commercial COMSOL 5.5 Multiphysics software. This is a computational fluid dynamics (CFD) model based on conservation
equations with the chemical reaction model of anaerobic digestion (AD) processes to investigate the influence of different horizontal circular extended
surfaces augmented to the inside digesters on the performance of the anaerobic digestion. Using four batch digesters, D1 with no extended surfaces
and D2, D3, and D4 have augmented with four horizontal circular extended surfaces of More >
