Abstract

The influence of pressure on permeation efficiency factor for vapour transfer T. Kozak and A. Majchrzycka Technical University of Szczecin, The Faculty of Mechanical Engineering, Poland Abstract The paper reports theoretical development of the cloth permeation efficiency factor for vapour transfer Fpd in the hyperbaric environment. Experimental investigations of Fpd were carried out in the hyperbaric chamber in air within the total pressure range p=0.1-5 MPa. The study was undertaken to determine the effect of the total gas pressure on the cloth permeation efficiency factor for vapour transfer. The results of experiments demonstrated a large influence of the total pressure on 1 Introduction Presented paper deals with the problem of thermal comfort inside the hyperbaric chamber, which is a typical experimental facility defined as a land-based, high pressure chamber which will accommodate divers at varying pressure to simulate the depth inside the chamber while the external press
