Local Nusselt Number Around Circular Cylinder!
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!!!!
I have the same problem... how did you solve it please?
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.
