hi all users.
I want to obtain the temperature profile in poiseuille flow.The temperature of walls is constant and the flow is without thermostat.the temperature that get in this way is five times larger than wall’s temperature ! .I think that it need the appropriate wall model for interaction between fluid and wall , and wall models in lammps(wall/reflect and …) aren’t useful for this.
am I right?
can I simulate this with wall models that is in lammps?
You can simulate models like this with LAMMPS. Do you
want an ideal wall or a rough (atomistic) wall? What kind
of interactions between the wall and particles do you want?
How are you measuring the temperature of the flow?
