Which turbulence zoning is to be used for numerical wind load generation on buildings?


The program RWIND Simulation offers an optional consideration of the k-ε and k-ω turbulence models for the numerical flow simulation. The turbulence parameters necessary for this can be specified manually or determined automatically from a user-defined turbulence intensity value. In the standard setting, the turbulence intensity is set to 1%. This value is based on a recommendation of the company CFD Support , which has many years of experience in the field of numerical fluid dynamics simulations.

In RWIND Simulation, the turbulence model is organized in the "Parameters of Simulation" menu under the "Turbulence" tab.

The interface menu in RFEM or RSTAB organizes the turbulence model for the automated calculation of wind loads in the background in the menu "Simulate and Generate Wind Loads" under the "Settings" tab.
