Direct wind tunnel modelling of natural ventilation for design purposes.

Summary

The investigation covers the three cases encountered in practice, i.e. wind alone, buoyancy alone and a wind and buoyancy combined. The wind tunnel is a very powerful tool for natural ventilation design on nondomestic buildings, where the design aim is to specify the size and position of purpose-provided openings. It offers more accuracy in the determination of wind effects than other techniques. From an analysis of experimental and theoretical results it is concluded that the direct technique is feasible for a wide range of building sizes. Some improvements have also been identified. Further work is also required to clarify why the observed values of discharge coefficients are larger than might be expected.
