Which of these models solves turbulent kinetic energy and specific dissipation?(a) K – omega model(b) K – epsilon model(c) RANS model(d) RNG – LES modelI have been asked this question in homework.My enquiry is from Turbulence Modelling topic in section Boundary Layers, Laminar & Turbulent Boundary Layers, Navier Stokes Solutions of Aerodynamics

Answer»

Correct option is (a) K – omega MODEL

Easy explanation: K – omega is ONE of the POPULAR turbulence model. It is a TWO-equation model which solves two transport equations –turbulent kinetic energy and specific dissipation. Turbulent kinetic energy determines the energy whereas the specific dissipation determines the turbulence scale.
