Default calculation of value of convective heat transfer coefficient for a bank of cylinders

hi guys
I am new at using ansys and the problem i have in hand is to find the cooling time for a array of cylinderical wires from 80degree celius to 50 degree celius
the conditions are
laminar cross flow over the cylinder
forced convection
I somehow managed to get the empirical fomulation of convective heat coefficient for a single wire using empirical corelations
but what should i do find the h for a in line configuration of cylinderical wires
I read that it can be done using CFX ansys but i am unable to do it
I know that the h will vary as the air flows over the cylinders in one row
Please help
an early response will be appreciated

you can mail me at , i can perform transient analysis in Ansys CFX to determine the cooling time.
