Hi everybody
I want to use heat pipe in a system for cooling. I want to work with fluent. actually I don't want to model heat pipe, because it needs a lot of time. I just want to see the effect of it on the system. for this reason I want to calculate an equivalent thermal conductivity of it and then use that value for heat pipe. but in fluent is that possible to give the software only themal conductivity value? and not the other properties, e.g Cp and density? |

You will have to provide all necessary physical properties of the material.
Nevertheless, in a steady-state simulation, the result will be independent of the values of c_p and density. Just make sure to provide "reasonable" values, for example a density of 10e6 kg/m³ will certainly lead to convergence issues. BTW: if you have questions specific to the software package fluent, please put them in the fluent subforum next time. |
