THE IMPACT OF TURBULENCE ON DRAUGHT.

Author(s) : FANGER P. O., MELIKOW A. K., HANZAWA H.

Summary

IN 3 EXPERIMENTS, FIFTY PERSONS, CLOTHED IN ORDER TO OBTAIN A NEUTRAL THERMAL SENSATION, WERE EXPOSED TO AIR FLOWS WITH LOW (LESS THAN 12%), MEDIUM (BETWEEN 20 AND 35%), AND HIGH (MORE THAN 55%) TURBULENCE. THE SEDENTARY SUBJECTS WERE EXPOSED TO SIX AIR VELOCITIES RANGING BETWEEN 0.05 M/S AND 0.40 M/S. AIR TEMPERATURE WAS MAINTAINED CONSTANT AT 296 K (23 DEG C). THE SUBJECTS WERE ASKED WHETHER THEY HAD FELT AIR MOVEMENT AND DISCOMFORT. ONE WAS ABLE TO DETERMINE THE PERCENTAGE OF PEOPLE DISSATISFIED BY THE FLOW AS A FUNCTION OF MEAN VELOCITY AND TURBULENCE INTENSITY. TURBULENCE INTENSITY HAS A SIGNIFICANT EFFECT ON THE PERCEPTION OF DRAUGHTS.
