Analysis of Articulated Manikin Based Convective Heat Transfer during Walking

Abstract

Using the articulated manikin at U.S. Army Research Institute of Environmental Medicine (USARIEM) as a model, the effect of the walking motion on the local convective heat transfer at various body sites was studied. The forced convective heat transfer coefficient (hc) was determined by the naphthalene sublimation technique. The results showed that the arm movement during walking, unexpectedly, diminished the local convective transfer coefficient. Increasing gait actually resulted in a decrease in hc, as measured on the arms and legs. On the non-moving body trunk, no significant difference in hc was observed with changing gait. When the manikin was held stationary and the chamber wind speed increased, a corresponding increase in hc was observed. Thus, during walking, motion of the swinging limbs, the 'pendulum' effect, tends to decrease the forced convective heat transfer as observed locally on the limbs. Keywords: Anatomical models, Convection heat, Transfer.
