Tubular Reactor

Model ID: 67


This tutorial example is very educational in explaining the PDE interface. It couples heat and mass balances to reaction kinetics. It is also a good example of scaling equations so as to create nice modeling geometries of systems with large aspect ratios.

In a tubular gas reactor, chemical reactions take place in a stream of gas that carries reactants from the inlet to the outlet. Mass and energy transport occur through a convection-diffusion and convection-conduction processes.

The 1D example examines a simplified model of a tubular reactor. It assumes that radial variations in compositions and temperature are small due to plug flow and heat-insulated walls. The 2D model includes a cooling effect from the outside of the cylindrical reactor.
