Abstract

A generalised thermal model for the determination of transient core and skin temperatures for
both clothed and unclothed operators has been developed. Healthy/sick and passive/active
operators have been considered in the analysis where the effects ofsickness and the addition of
muscle heat are i,n·estigated. The developed model has been validated against the results
available in the literature. It is also observed that core and skin temperatures anained by an
operator exposed to various enl,lironmental conditions fo r a long time correspond to the steady
state temperatures. Though the model is generalized to take into account various aspects ofthe
problem, yet it is comp rehensive to be used in practice.
