Abstract

In continuous-flow enzymatic microbioreactors, enzymes on the channel walls catalyze reaction(s) among feed chemicals, resulting in the production of some desirable material or the destruction of some undesirable material. Computational models of microbioreactors were developed using the CFD-ACE+ multiphysics simulation package. These models were validated via comparison with experimental data for the destruction of urea, catalyzed by urease. Similar models were then used to assess the impact of internal features on destruction efficiency. It was found that triangular features within the channels enhanced the destruction efficiency more than could be attributed to the increase in surface area alone.
