• The permeability is given by the hydraulic diameter and the product of the friction factor f_l and the Reynolds number Re. The former is obtained through the wire diameter and the porosity of screen wicks. The latter must be evaluated experimentally since it is influenced by the specifications of the screen and the wick thickness. Experiments have been conducted to investigate the effects of the characteristics of the wick on the permeability. The value of f_lRe decreases with the increase of the porosity, but still varies with the ratio of the wick thickness per layer to the wire diameter. A correlation between f_lRe and the ratio including the porosity is proposed. The permeability predicted by the correlation shows good agreement with the experimental results.
