Hi friends,

Currently I am facing the problem to determine simulation exit gas composition in % by volume. I have the gas composition from gasification result such as CO : 0.004431, CH4 : 0.0001466 and O2 : 0.01 in mass fraction.

My question to you all, how to convert the exit mass fraction into % by volume. My purpose is the current result of my gasification study will be compared with others work which are written in % by volume.

Anybody who can help me to assist my problem immediately, will be highly appreciated.

Thank you very much

Bye Adi

Try mole fractions!

For gases mole fractions and vol-fractions are the same. This is due to the property of gases that 1 mole of any gas occupies the same volume at the same conditions (pressure and temperature).

Is'n that called the law of Boyle and Mariotte?

Hey friend,

I am quite new in simulation and using ANSYS. Can u tell me please, how i can get the simulation exit gas composition, what u have done?
Eagerly waiting for your reply friend..
Thank you..
