1.	Though the applicability of the realizable k-ε model and the RNG k-ε model are almost the same, the realizable k-ε model is ___________ when compared to the RNG k-ε model.(a) more accurate and converges easily(b) more stable(c) linear(d) more consistentThe question was posed to me in a national level competition.My doubt stems from Turbulence Modelling in division Turbulence Modelling of Computational Fluid Dynamics
Answer» Right choice is (a) more ACCURATE and converges easily Easy EXPLANATION: The realizable k-ε model and the RNG k-ε model have the same benefits and APPLICATIONS. But, the realizable model GIVES more accurate results and it is easy to CONVERGE when compared to the RNG k-ε model.
