CFD simulations

"The validation study shows that the SST k-u turbulence model provides the most accurate results..."

View

Roof Geometry

"The internal air flow and the volume flow rate show a clear dependency on the roof geometry."

View

Roof Inclination

"The indoor air flow pattern changes with changing roof inclination angle."

View

Double-span Roof Geometry

"reducing the opening ratio from 1 to 0.5...increases the volume flow rate".

View

Volume Flow Rate

"To improve the volume flow rate the roof inclination angle must be considered"

View

Eaves Configuration

"The eaves can significantly increase the volume flow rate."

View

Outlet-opening Geometry

"The building geometry near the outlet-opening plays an important role in the ventilation."

View

Outlet Opening Position

"The vertical position of the outlet opening slightly increase the volume flow rate."
