Dear all,
In my simualtion domain, I need to use mixture of gas ( N2 gas with 20% CO2) at INLET in ANSYS Fluent.
Mixture model, and species model, may be these models work. Actually, I need your support to notify the model and how to put the above specifications on that model too.
Regards
Hi,
U can find different species mixture when u turn on the species transport model...If u select any "hydrocarbon (example. methane etc)"-air mixture, u will get the option for specifying CO2, H2O etc mass fractions at the boundaries (eg. inlet etc)...U can specify CO2 mass fraction as 0.2 and all others as 0. If u r using fluent, the code will automatically take remaining 0.8 mass fraction for nitrogen.
You can use VOF option to specify mixtures or species transport model
You can define the properties your own mixture in UDFs, and compile it to Fluent.
You can probably get a lot of help from the Flunt manual in the MATERIALS and UDF part. Let me know if you need more help.
I want know how to inlet co2 and o2 and h2o in asyes to emission from person
