Abstract

The paper reports theoretical development of the cloth permeation efficiency factor for vapour transfer in the hyperbaric environment and experimental results of the evaporation coefficient and permeation efficiency factor for vapour transfer. Investigations were carried out in hyperbaric air and helium rich mixtures. Experimental results demonstrated a large influence of gas pressure on the parameters being investigated.
