Numerical analysis of computational fluid dynamics (CFD) is one of technologies that can be minimized the experimental cost. This paper is presents the isothermal swirling turbulent flows analyses in a combustion chamber of an unconfined burner. There are many types CFD models that can be used in order to simulate isothermal flows with the Reynolds-Averaged Navier-Stokes (RANS) models involving the two equations of calculation. The RANS of various models, including standard k-ε, RNG k-ε and realizable k-ε turbulence approach method was applied. These analyses were studied to define the effect of flow axial velocity and tangential velocity that particularly to obtain the center recirculation zone (CRZ). The swirler is used in the burner that significantly influences the flow pattern inside the combustion chamber. The inlet velocity, U0 is 30 m/s entering into the burner through the axial swirler with SN = 0.895 that represented a high Reynolds number, Re. These studies also performed using ANSYS Fluent to evaluate the effect of difference's RANS models. Transverse flow field methods have been used to determine the both velocity's behaviour behind the axial swirler downstream. These results of axial and tangential velocity were normalized with the U0. The velocity profiles' behaviours are obviously changed after entering the swirler and slightly different pattern of each model.
