How to Use
Choose the turbulence model and fill in the required parameters in the orange area.
The parameters are unit-agnostic, check that all the values are using the same system of units.
The required input parameters could be reference length (e.g. a pipe’s diameter or a vehicle’s length), a reference free-stream velocity, kinematic viscosity of the fluid, turbulent viscosity ratio (choose a value between 1 and 10) and turbulence intensity level (choose a value between 0 and 1).
Output values are shown in the green area. These values will change according to the selected turbulence model and they could be Reynolds number, turbulence length scale, turbulent intensity, turbulent dissipation rate, specific dissipation rate and turbulent viscosity.
