Effective thermal conductivity of a screen wick
Abstract
Effective thermal conductivity of a screen wick filled with working fluid in the case that phase transformation is not considered was calculated by the equation of Maxwell or the equation of Gorring and Churchill. Both of the equations are described as a function of thermal conductivity of working fluid and wick materials, and porosity of the wick. Although, there is much difference for the same porosity, and it is difficult to estimate porosity itself. Here, with consideration of diameter of a wire for a screen wick, mesh number, layer gap and coefficient of shrinkage, the equation to calculate effective thermal conductivity of a screen wick was derived.
