Impact of Estimating Thermal Manikin Derived Wind Velocity Coefficients on Physiological Modeling
Abstract
It is well understood that thermal strain will occur from working in hot conditions or at moderate to high work rates, and that this impact varies with wind velocity. One method for addressing the wind velocity effect on insulation and evaporative resistance includes conducting standardized thermal manikin testing followed by additional custom tests. This current method tests at the standard one wind velocity (0.4 m/s) as well as at two additional wind speeds, for a total of six tests (i.e. 3 for insulation and 3 for evaporative resistance). This process seeks to create a set of measures to produce the gradient effect of wind, in order to obtain associated coefficients. This report outlines mathematical methods for determining reasonable estimates of wind velocity effect on biophysical measures using only the standardized test methods. This new method will empower using the standard approach, for modeling purposes, while economically adding a simpler method for determining wind velocity effects.
