Abstract
The purpose of this paper is to report fundamental data for natural ventilation caused by the ventilator which is equipped with building. We report the results of some mesurements on property of space static pressure surrounding model in turbulent boundary layer and discuss them in this paper. The outline is described bellow. 1) Mean wind velocity of air stream surrounding model gets smaller as the ratio of model height to turbulent boundary layer thickness gets smaller. 2) Space statical pressure surrounding model gets smaller as the ratio of model height to turbulent boundary layer thickness gets smaller. 3) Mean wind velocity gets smaller and space static pressure gets bigger as measured point gets nearer to windward surface of model regardless with property .of approach flow. 4) We used method of measuring space static pressure, 'which is proposed in this paper, and obtained satisfactory results that we can measure space statical pressure where we mesaure space wind direction.
