Title The natural convection flow about the human body.
Bibliographic information Jan. 1973, Vol.12, No.133, p.11-19. Illus. 6 ref.
Abstract This study arose as a result of work by the British National Institute for Medical Research on man's acclimatisation to extremes of cold. The natural convection flow of air about the human body was investigated and it was shown that a boundary layer several centimetres thick, with a maximum velocity of 50 cm/s is established over a naked human for an ambient temperature of 15°C. This layer acts as a transport path for small particles such as pollens and skin scales. The convective flow is considered to play a part in the transmission of airborne infection. The results of these studies find applications in the design of operating theatres and protective clothing.
