This research report consists of four sections : report (I) which has already presented in the preceding number and report (II) which is presental here and report (III), (IV) which will be presented in the next numbers. In report (I), (II), (III) we describe about the measurement of the velocity of the wind near the building wall and the velocity in the corridor opened to the outdoor which is set on the exterior wall of the building. In this experiment, we use the single model of the apartment house and a few models arranged variously, 24 hot wire anemometers are set on the wall of the model. Report (I), (II), (III) aim at reaching some principles for setting the balanced-flre terminals and another principles for designing the corrider opened to the outdoor. In report, (IV), we describe about the analysis of the turbulence of the air flow around the bluff body on the building wall and the analysis of the surface pressure of the wall, In this experiment, we use the two dimensional fence model and block model on the flat plate and the various kinds of electronic instruments, for example, linearizer, correaltor, A-D convertor, analogue and digtal computers, etc. Report (IV), aim to clarify the diffusion of the exhaust of the gas boiler around the bluff body on the building wall and to reach some principles for deciding the position of the balanced-flue terminals which is set near the bluff body.
