In this study, we tried to validate FLUENT solver model and domain setting for the problem of convective heat transfer in multiple tithe bank under transitional zone. We have paid special attention to verify proper boundary conditions and the grid convergence. Through validation work, It is found that unsteady solution method with two-dimensional simulation domain can produce reasonable accurate results compared with existing experimental data. Simulation results with steady solution generates relatively large error. We found that both steady and unsteady method for three-dimensional domain shows acceptable accuracy. Further parametric study for deriving correlation from transverse and longitudinal pitch is currently underway.
