EXAMINATION OF FREE CONVECTION AROUND OCCUPANT'S BODY CAUSED BY ITS METABOLIC HEAT.

Author(s) : HOMMA H., YAKIYAMA M.

Summary

FREE CONVECTION, WHICH IS CAUSED BY THE METABOLIC HEAT AROUND A HUMAN BODY IN A ROOM, WAS EXAMINED BY THE FLOW VISUALIZATION OF INFRARED THERMOGRAPHY AND SMOKE WIRE PHOTOGRAPHY AND BY HOT WIRE ANEMOMETRY. THE EXPERIMENTS WERE CARRIED OUT USING HUMAN SUBJECTS AND A HEATED RECTANGULAR MANIKIN, WHICH IS A SIMULATED MODEL OF A STANDING MAN. THE PAPER REPORTS THAT: (1) A HUMAN BODY IS ENVELOPED BY AN UPWARD AIRSTREAM, THE VELOCITY OF WHICH CORRESPONDS TO THE ACCEPTABLE HIGHEST AIR VELOCITY OF COMFORT ; (2) THE VOLUME FLOW RATE IN A PLUME ABOVE A BODY IS SEVERAL TIMES LARGERTHAN THE VENTILATION REQUIREMENT ; (3) THE HEAT TRANSFER AT ANKLE LEVEL IS TWICE AS LARGE AS THAT ON THE UPPER BODY.
