My case involves homogeneous and heterogeneous reactions in porous media. In the cell zone condition panel I can only turn on/off the homogeneous reactions (in each phase) in a zone. When the geometry is only includes a zone, there is no problem, but when it includes more than one zone and I want that the reactions take palce only in a specified zone, it does not permit to enable or disable heterogeneous reaction (unlike homogeneous) in zones. Hence this reaction occurs in all zones and leads to sharp increase in temperature and finally divergence.
Thanks you in advance.
how your zones are divided, that is not much clear.
still if your are talking about propeller design it can be done through maintaining different chambers.
otherwise in a continuous media first determine mass transfer coefficient and then accordingly flow of rectant can be done in order to prevent any kind of reaction in different zones.
