EN

Visualizations and numerical values are presented of some fluid flow and heat transfer parameters in a biogas reactor with and without a stirring frame. Results obtained through mathematical modeling and computer simulation with ANSYS 8.0jFlotran are used for a heat transfer calculation method for the investigated bioreactor type.
