I would like to know if it is possible to set reactions in porous media by using the software Fluent, so that the porous media acts as a reactant. I need to model a problem that consists in a filter with a fixed bed (calcium hydroxide) that reacts with a gas (SO2). Is it possible to take into account the variation in porosity and permeability of the fixed bed while the reaction occurs?

of coruse it can be done.you can use a udf to change the porosity
