Summary

DEALS WITH THE PROPERTY OF EDDY KINEMATIC VISCOSITY BY THE MEASUREMENTS OF TURBULENCE IN 5 MODEL ROOMS WHICH DIFFER IN SIZE. THE MAJOR FINDINGS ARE: 1. THE LINEAR RELATION EXISTS BETWEEN THE OUTLET AIR VELOCITY AND THE MEAN VELOCITY. 2. THE AVERAGE TURBULENCE INTENSITY OF A ROOM IS INDEPENDENT OF THE OUTLET AIR VELOCITY AND THE SCALE OF A ROOM. 3. THE TURBULENCE AT THE CENTRAL AREA OF A ROOM, THE TURBULENT CORE ZONE, IS THOUGHT TO BE CLOSE TO ISOTROPIC. 4. THE AVERAGE LENGTH OF THE MEAN EDDY OF A ROOM IS PROPORTIONAL TO THE SCALE OF A ROOM. 5. A RELATION IS DERIVED FROM BOTH MEASUREMENTS OF MEAN AIR VELOCITIES AND THE TURBULENCE OF A ROOM.
