get unlogic profil of reactant and product concentration in combustion reaction
Im tryin to simulate combustion in combustion chamber. the fuel is gas pyrolysis (ch4, c2h6, h2, and co) it enter the domain from the bottom of the chamber. i also have air input which comes into chamber from holes at the side of chamber.
i use 3 interfaces :
-heat transfer in fluid
-transport in diluted species
the problem is, concentration result seems so unlogic because there are some spot where the reactant increase and also only a little spot the product exist. and the product is decrease.
hopefully anyopne could help me to get out from this problem.
Hi. Could you please post some pictures of your case so that people here can understand better your problem? For example velocity field, species (reactants and products) concentration field, temperature and heat release?
