Measurements of the Thermal Conductivity of Propane in the Supercritical Region

摘要: Measurements of the thermal conductivity propane performed in a coaxial cylinder cell operating steady state conditions are reported. The measurements were carried out along eight quasi-isotherms above critical temperature. present data cover temperature range from (370.83 to 381.00) K, and pressure (0.1 15) MPa. An analysis various sources error leads an estimated uncertainty approximately 3 %. parameters background equation determined experimental order analyze enhancement as function density. On basis measurement more than 500 points, phenomenological is provided describe propane, 369.825 K 600 densities up 550 kg·m–3. This can be generalized calculate supercritical behavior for any fluid.
