I have a S.I.M.P.L.E. scheme Code. I want to add Turbulence flow in my code. How can I do that? Please help me

Initialisation of Velocities, pressure, turbulent fields

For each Out Iteration of SIMPLE { Solve Momentum equation Solve Pressure correction, and correct velocities Solve Turbulence equations (for example k and e) Update turbulent viscosity }

Repeat until convergence is achieved.

Thank you. I also want to know how to apply (Y+) in my code for different layers of Turbulence (Inner Zone, Outer Zone).
