Air Flow Velocity in Clothing for Thermal Manikin and Human Body

We measured the air flow in clothing microclimate for a standing thermal manikin and human bodies and obtained the following results : (1) The air flow existed at chest, abdomen, back, arms and legs. (2) The difference of the air permeability of clothing did not affect the air flow velocity on the torso but affected it at the arms and legs. (3) The air flow velocity on the torso depended on the condition whether lower sleeve edges and cuffs were open or not, while the air flow velocity at the arms and legs was not affected by the condition of the lower sleeve edges and cuffs. (4) The air flow velocity in clothing microclimate was 0.10 ± 0.05m/s except near the lower sleeve edges and cuffs.
