Hello everybody,
I am doing one turbulent flow simulation in fluent. But I could not understand how to decide value of K and epsilon, or "intensity and length scale", or "viscosty ratio"??? ![]() ![]() ![]() |

IF you know Turbulent intensity at Inlet you can choose intensity and hydraulic diameter .it's the best choise
else leave the default values unchanged |

for idraulic diameter you consider this equation
De = 4 A / P where A is area and P is perimeter; in effect if you have a cylinder the hydraulic diameter is equal to diameter of cylinder |
