Heat gain from thermal radiation through protective clothing with different insulation, reflectivity and vapour permeability

The heat transferred through protective clothing under long wave radiation compared to a reference condition without radiant stress was determined in thermal manikin experiments. The influence of clothing insulation and reflectivity, and the interaction with wind and wet underclothing were considered. Garments with different outer materials and...

Non-evaporative effects of a wet mid layer on heat transfer through protective clothing

In order to assess the non-evaporative components of the reduced thermal insulation of wet clothing, experiments were performed with a manikin and with human subjects in which two layers of underwear separated by an impermeable barrier were worn under an impermeable overgarment at 20°C, 80% RH and 0.5 ms-1 air velocity. By comparing manikin...

Interaction effects of radiation and convection measured by a thermal manikin wearing protective clothing with different radiant properties

As part of the EU funded research project THERMPROTECT ('Thermal properties of protective clothing and their use') this paper deals with manikin experiments on the effects of heat radiation at different wind speeds, considering aspects related to the reflectivity of the clothing. A heated thermal manikin 'Newton' was operated with a constant...
