Dinesh_ 0 Report post Posted September 5, 2017 Hi all For using Realizable K epsilon Turbulence model .If i use intensity and viscosity ratio What will be the optimum value of below said parameters for Internal flows Turbulent velocity scale = Turbulent viscosity ratio = Quote Share this post Link to post Share on other sites
Ravi H 4 Report post Posted September 5, 2017 Hi Dinesh, Turbulent velocity scale : is the average velocity at the inlet Turbulence viscosity ratio: viscosity ratio, , is the ratio between the turbulent viscosity, , and the molecular dynamic viscosity, . The turbulent viscosity ratio is directly proportional to the turbulent Reynolds number. Typically, the turbulence parameters are set between 1 to 10. here viscosity ratio 10 is good enough.
