Calibrated reduced order models for rectangular floor-plan and CFD simulations with recalibrated turbulence models for general building topologies
Target building with surrounding conditions, up to neighborhood scales. Input geometry compatible with CityGML and CityJSON formats
To evaluate natural ventilation in buildings, the input and the output formats are also compatible with EnergyPlus software to perform airflow network analysis
User must upload the building geometry file and the list of wind incidence angles required. The geometry should be split in as many surfaces as the level of detail for pressure coefficients be required.
Automatic procedures generate the virtual wind-tunnel, mesh the domain and configurate the CFD simulation following the COST actions guidelines (see this paper).
RANS equations are solved using a finite-volume based steady-state solver. Turbulence is modeled recalibrated RANS models for ABLs (see this paper). One simulation per wind angle is performed in our clusters.
Surface-averaged pressure coefficients are computed on each selected surface. Snapshots with main flow patterns are also generated.
Results data is returned to the User. It includes a .csv table of Cp per surface and wind angle, .idf file updated (if required), .vtk files for specific post-processing and other statistics.
