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.
