Forced convection around the human head.

1. The parameters determining the forced convective heat loss from a heated body in an air stream are outlined. 2. Local forced convective heat transfer distributions around the human head and a heated vertical cylinder at various wind speeds in a climatic chamber have been found to be similar and related to the aerodynamic flow patterns. 3. From the local convective coefficient distribution, values for the overall convective coefficient h-c at various wind speeds have been evaluated. These are seen to agree closely with existing whole body coefficients determined by other methods.
