Comparison of model and full scale natural ventilation studies.

Undertakes a comparison of full scale and model scale internal velocities of naturally ventilated rooms. The FSEC Passive Cooling Lab, an experimental building with a fixed roof supported by columns, whose floor plan and ceilings are reconfigurable, located at Cape Canaveral in Florida, is the building used in this study. The full scale tests were conducted during evening and early night to provide an almost thermally neutral atmosphere, during February and March 1982. The results show small disagreements between full scale and model internal velocities for flows not driven by mean pressures. This is partly explained by the inexact modelling of the atmospheric turbulence of speed and direction. For flows which are mean pressure driven, agreement is quite good.
