N2 - The influence of biofilm geometrical characteristics on substrate mass transfer and conversion rates is evaluated. A spatially two-dimensional model is used to compute the laminar fluid flow, substrate mass transport, and conversion in irregularly shaped biofilms. Numerical results show that increased biofilm roughness does not necessarily lead to an enhancement of either conversion rates or external mass transfer. The average mass transfer coefficient and Sherwood numbers are found to decrease almost linearly with biofilm area enlargement in the flow regime.
