Numerical simulation on aerodynamic field of self built cold tangentially fired boiler was conducted.Four turbulence models such as Standard k-ε
RNG k-ε
Realizable k-ε and Reynolds stress model(RSM) were applied to obtain the velocity distribution of the upper primary air
lower primary air and the tertiary air.Moreover
the simulated results were compared with the high-precision PIV(Particle Image Velocimetry) test results.The results showed that
the calculating time of the Realizable k-ε model which can accurately analyze the turbulent characteristics was obviously less than that of the RSM model.
