B.C and Grid size LES Fluent

I am using fluent to run a LES simulation on a reactor which has two inlets and a outlet.
The inlet jet reynolds number is about 1000 and the inlet is rectanguar (aspect ratio 1:2)..
I calculated the kolomogov scale based on this Re and Lo being the width of the reactor chamber to which the inlets connect.. and i found that to be of the order of 15microns.
I thne made a grid and when I checked the grid info, the minimum cell volume is of the same order as the kolmogorov scale..
The inlet condtions are uniform flow and the outlet condition is outflow.
I have read that you need to have a reasonable good input BC (perhaps from that of K-epsilon model).. Can anyone help me in guiding towards the right path..
