چکیده انگلیسی
Absolute measurements of the thermal conductivity of n-hexane performed in a coaxial cylinder cell operating under steady state conditions are reported. The measurements of the thermal conductivity of n-hexane were carried out in the liquid along nine quasi-isotherms below the critical temperature (Tcâ¯=â¯507.82â¯K), in the low-pressurized gas at some temperatures below the critical temperature, and in the compressed gas along nine quasi-isotherms above the critical temperature. Additional thermal conductivity measurements were also performed in the liquid and the gas along the isobar at 0.101325â¯MPa and in the vapor close to the saturation curve for temperatures below the boiling temperature (Tbâ¯=â¯341.865â¯K). The present 577 data cover roughly the temperature range from 293â¯K to 612â¯K and the pressure range from 0.01 to 40â¯MPa. An analysis of the different sources of error leads to an estimated uncertainty of approximately 1.5%. The experimental results are correlated separating the additional contributions of the temperature effect and the density effect (in the density range from 0 to 670â¯kgâ¯mâ3). A brief comparison is shown with previous experimental measurements of the thermal conductivity of n-hexane.
