Hi
I try to calculate nusselt number in a pipe with 2.5 cm diameter and 2m long. my tube have a constant heat flux and i want to calculate local nusselt number along the tube. I go to XY Plot>Wall fluxes> surface heat transfer coef. then i multiply D/K with the min of diagram to calculate fully developed nusselt number and it never was 4.36. it is around 0.8 that isn't acceptable. please help me thanks |

Are you in the laminar flow regime? What are your inlet and outlet conditions?
