The permeability is given by the hydraulic diameter and the product of the friction factor f_ι by 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. The experiments have been conducted to investigate the effects of the characteristics of a wick on the permeability. The value of f_ιRe decreases with the increase of the porosity and still varies with the ratio of the wick thickness per layer to the wire diameter equating the porosity. A correlation of f_ιRe is proposed by this ratio involving the porosity. The permeability predicted by the correlation shows good agreement with the experimental results.
