constant wall temperature of the channel

Weiqiang Liu · February 15, 2019, 15:56

hello, All:

I am doing a micro channel catalytic combustion of methane simulation. When I was doing some literature reviews, I found some authors just set the wall thermal boundary condition as constant temperature like 1500K.

I am wondering what is the meaning of setting a constant wall temperature. In real application, if you can impose some variant heat flux on the wall to keep the wall temperature constant during chemical reaction. Then what is the meaning to keep this temperature constant?

I mean why those author just set some adiabatic or convective thermal boundary condition to simulate real situation. I think this makes more sense.
