Efficient Numerical Methods for the Simulation of Flow Reactors

We describe recent developments in the design of numerical methods for the simulation of heat transport and chemical processes in ow reactors. For viscous ow in the low-Mach-number regime, we use a stable finite element method for discretizing the compressible Navier-Stokes equations which is oriented by the incompressible limit case. The ow and chemical equations are solved as a fully coupled system by an adaptive defect correction method. This approach is illustrated by several examples of ow reactors including a case with steep temperature gradients. The eÆciency and predictive capability of our codes are verified by comparison with traditional ad-hoc methods and experimental data.
