CFD - Opis:
- The paper reviews selected methods of agricultural biogas production and characterizes their technical and technological aspects. The conditions of the anaerobic fermentation process in the reactor with adhesive skeleton bed were analyzed. The required technological criteria for the production of biogas from a substrate in the form of pig slurry were indicated. As part of experimental studies, evaluation of the biogas replacement resistance coefficient and the permeability coefficient as a function of the Reynolds number were made. The method of numerical simulation with the use of a tool containing computational fluid dynamics codes was applied. Using the turbulent flow model – the RANS model with the enhanced wall treatment option, a numerical simulation was carried out, allowing for a detailed analysis of hydrodynamic phenomena in the adhesive skeleton bed. The paper presents the experimental and numerical results that allow to understand the fluid flow characteristics for the intensification of agricultural biogas production.
