Hello,

        How to calculate Wall Temperature when you have more than one wall surface, 

                                 Fin area/Total area

                                and Total heat Transfer area/volume between plate  using AnsysFluent?

 

Thanks,

Sam

You already have access to it at walls. What is still missing?

[Sam001]

Amine,

          Am I to use the net for the overall Wall Temp?

Thanks,

Sam

Depends which wall you want to the data for. You need to work out what you want data for. 

[Sam001]

rwoolhou,

              ok, what of fin area/Total area?

[DrAmine]

More details: what do you want to Do?

[Sam001]

Amine,

           finding Stanton number?

Regards,

Sam

[DrAmine]

So you need averaged values along the wall (say like area-weighted) and the whole area of the wall. Stanton is: St = Nu / (Re * Pr) so you need to use some "global" charateristics for your flow. Fluent provides Surface Stanton Number as post-processing variable based on the reference values.

[Sam001]

Amine,

          Please, can you break down the term "global" characteristics?

Regards,

 

Sam

[DrAmine]

Reference Temperature, Reference Length for example to define Nu and Re.

[pssjn]

is it possible to calculate the wall temperature of 'zero thickness wall'? what is the best way to calculate natural air ventilation rate of a room in fluent?

Best regards,

Farhan

Yes you can. Please mark this as is Solved and open new discussion for your new question.
