Accurate and reliable computational fluid dynamics (CFD) simulations are essential for the assessment of
cross-ventilation of buildings.
To determine which CFD models are most suitable, validation studies are required.
Therefore, the objective of this simulation is validate a 3D steady RANS simulation of cross-ventilation using OpenFoam (SimScale)
The validation is based on the velocity parameter
The RANS simulation here is conducted with the realizable k-e turbulence models.
The experimentally observed direction of the incoming jet, but all RANS models fail in
It is concluded that choice of the RANS using SimScale Plataform actually produces good results
