When fluent sets the mixed gas, there is no mixed gas in the material type, so how to choose the mixed gas at the ash bottom?

FLUENT should use two-phase flow model to simulate mixed gas, first set up calculation model, and then set up other specific things.

Only the properties of simple medium are set in the material type, that is to say, if you want to use mixed gas, there are two ways for you to go now:

Firstly, two different media are defined by using two-phase flow model.

Secondly, the physical parameters (viscosity, specific heat, etc.) are directly obtained by using the single-phase model. ), and then create a new medium in the material menu and set the physical parameters of the mixed gas.

Generally speaking, it is more scientific to make mixed gas by the first method. Of course, if we only focus on the gas flow and heat transfer after mixing, we can use the second method.

Finally, I suggest that you go to Baidu Library to learn fluent Chinese Raiders in the next step. Learning fluency requires a lot of examples, but the most important thing is that you have a solid foundation in advanced fluid mechanics and computational fluid dynamics.

There is a long way to go in Xiu Yuan, and I will go up and down. * * * Whatever!
