Hello guys,

I am working on 'Flow & Heat Transfer over a circular cylinder''. I am using c-mesh and constant flux (isoflux) boundary condition at the cylinder surface.

Can anybody please tell me how to calcualte 'Local and Average Nusselt Number' at cylinder surface using FLUENT?

I tried to calculate local Nu but it is not in agreement with the experimental results.

I would really appreciate your help. Thanks!!!!

Hi there,

I just used

xy plots > wall fluxes > nusselt number

select the boundary on which u want to plot.

make sure u put the right length in the reference values section.

e.g. if u hv a cylinder of diameter 2 m, set this as 'length' in the reference values.

thanks
