Examination and selection of suitable methods for measuring the thermal conductivity of liquids in Spacelab
Abstract
A steady-state device for measuring the thermal conductivity of liquids onboard Spacelab is described. The experiments will permit determination of thermal conductivity at near-zero gravity while eliminating the effect of free convection. Measurement of heat conduction and sources of error are discussed, and a theoretical analysis of steady-state and nonsteady-state procedures is presented. The steady-state approach was selected in order to minimize errors. The construction of the measuring cell is explained with attention to the choice of materials.
