Effect of fluctuating wind direction on cross natural ventilation in buildings from large eddy simulation

A large eddy simulation (LES) program with the Smagorinsky subgrid-scale model has been used to study cross natural ventilation in buildings, which has experimental data available from on-site measurements and a wind tunnel. Since natural wind changes direction over time, it is hard to reproduce this effect in a conventional wind tunnel where the “wind” direction is fixed. There are discrepanci...

Experimental and numerical study of natural ventilation in four-sided wind tower traps

In the past, wind towers were applied as the main architectural part of building construction in the desert areas of Iran. These almost high structures were used as cooling load suppliers at residential buildings. In the present study, the effect of symmetric four-sided wind tower in flow induction to the bottom space has been analysed by using a wind tunnel and numerical simulations. In the nu...

Study of Natural Ventilation in Buildings with Large Eddy Simulation

With the discovery of many economic, environmental, and health problems in sealed and mechanically ventilated buildings, the concept of natural ventilation has been revived. "Buildings that breathe" have become more and more desired by ordinary people and architects. Although natural ventilation is conceptually simple, it is difficult to design and control. At present, methods to study natural ...

Numerical Simulation of Interference Effect on Dynamic Wind Loading of Tall Buildings in Close Proximity by Large-eddy Simulation

We attempt to compute the dynamic wind loads on tall buildings in close proximity with large-eddy simulation. Computation is attempted on two building geometries on which strong interference effects have been reported in previous wind tunnel studies. The computation uses a commercial code and a simple model of turbulence characteristics of the incident wind flow. The computed along-wind and acr...

Natural Ventilation: Analysis of Indoor Airflow in an Assumed Cubic Building with Opposite Openings by CFD Investigations

The natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. The wind power injects outdoor fresh air into the building. A good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. A serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...
