I have remarked that in several turbulence models where the turbulent kinetic energy is solved, the dissipation term appears as:
Code:
- fvm::Sp(alpha*rho*epsilon_/k_, k_) and I was wondering the reason behind this piece of code. ¿Does it give some stability? As far as I see, if all the left input is constant, it means that the contribution of epsilon on the equation will be affected by the factor k_calculated/k. ¡Thank you for your answers! |
