simulation on cooling tower
hi, everyone. now i handle a project about simulation on cooling tower, can i knw can i include the air humidity and make up rate so that my result more accuarate?
|
can anyone told me tis isint a limitation.

No, don't use water, just use air and then there is the field below where you can also select High Machnumber option or laminar and turbulent. Here you can also find "humidity". The relative humidity can then be set in the initial settings in the wizard and in the boundary conditions for flow etc.
But if this makes your results more accurate is not certain, it depends on the kind of results you are interested in. You should also not add random things to make results correct, the boundary conditions you apply should mirror the reality. Using humidity when there is none in reality is not simulating the reality it would be making the results the way you want it to be. |

If there is no water at all except the humidity you won't need water as a fluid subdomain. It depends on the model and what you want to simulate. I don't know what is needed in you model without a description or pictures.

Ok, but do you really need the water. Since FloEFD or FloWorks is not capable of calculating phase transition, you won't have water boiling and becoming steam or the other way around. So if the water has a certain temperature but you are not interested in the flow of the water it selfe but the flow of the air and the temperature change in the air you could maybe simulate the surface of the cool water with an approximation of a fixed temperature on the surface of a solid. Or separate the water with a thin solid sheet where you apply a self-defined solid material with super thermal conductivity to realize an ideal contact between water an air.

In this case I would use the thin super thermal conducting solid to separate the water from the air.
