COMBUSTION MODELS

Hello to everybody!

I would need to know what's the best strategy to use STAR-CD combustion models for combustor simulations. More in detail, I wonder wether EBU model is suitable in all conditions or if it's better to use Hybrid model or Combined Time Scale Model. Moreover, for Hybrid model and ComTime Model I would need a whole set of coeffcients for methane combustion, using first a single reaction scheme (CH4+2O2-->CO2+2H2O) and then a 2-reactions scheme (CH4+1.5O2-->CO+2H2O, CO+0.5O2-->CO2). I will be happy to receive comments from everybody

Thank you in advanve

Dear Stefano,

According to my experience COMTIME model yiels the most realistis results.
