negative index in product of combustion
Posted Jun 25, 2013, 9:26 PM EDT Chemical Reaction Engineering Version 4.4 3 Replies
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.
