Hi everyone

I´m simulating a solar receptor where i need to remove the heat from the receptor with the help of a heat exchanger, in the receptor domain i use air as a fluid, but in the heat exchanger domain i need to use water to remove the heat and then quantify it, but the issue is that i can´t work with these two different fluids (and properties) at the same time, how can i do that?


Thanks in advance.

Thanks in advance.

You should define two zones, one for air and one for water and specify properties to each one.

Sure, i understand that, in gambit i already define both zones, but when i try to specify the different fluids properties for each it´s not possible, both zones works with the same fluid and i need air in one zone with polynomial properties and constant properties of water for the other zone.

Is water included in material panel?!

yes, it´s included, but, if i change it to water, it change it to all the domain, and don´t just to the heat exchanger domain. I need to separate both fluids (water and air). It´s seem strange to me, because when i do the geometry and mesh in gambit, i declare both fluids as separated.
