Performance Comparison of Three Turbulence Models in Tuyere Jet Numerical Simulation

Standard two equation model, RNG two equation model and zero equation model are commonly used in HVAC engineering. In this paper, three turbulence models are introduced. And deflection grille air jets are simulated with them. Compared with the other two equation model, results show that using the standard equation model, whether in axial velocity attenuation or in fracture surface velocity distribution, the simulation is closest to the data measured. While using of zero equation model, the simulation would have great difference from the actual test.
