| Outline of Final Research Achievements |
The first purpose of this study was to establish the observation method of the airflow velocity in clothing（hereafter AVC). The AVC was observed using tuft method, hot wire anemometer, supersonic wave anemometer, thermography, etc. Finally, we adopted the hot wire anemometer fixed within resin cylinder of 30 mm inside diameter by 63 mm in length.
The second purpose was to observe the relationships between the AVC and the various conditions such as clothing, surrounding wind velocity, room temperature, body surface temperature, posture, body motion, etc. using the manikin or human subjects. The AVC at the chest area was about 0.4m/sec, it tended to be highest in all areas. The AVC was higher in 18 degrees centigrade condition than in 23 degrees one in most cases. The gradual increase of frequency of the body motion was accompanied by the increase of the AVC.
