Thermal conductivity and thermal diffusivity of liquid aromatic hydrocarbons undistorted by radiation heat transfer

摘要

The values of thermal conductivity and thermal diffusivity are measured for seven substances (benzene, toluene, 0-n-m-xylenes, ethylbenzene, and isopropylbenzene) at temperatures T = 293-593 K and pressures P = P{sub}S - 30 MPa. The obtained values of thermal conductivity and thermal diffusivity differ from the reference values by not more than 15. The generalizing dependences are given, which describe the thermal conductivity, thermal diffusivity, and heat capacity per unit volume of ii-alkanes, alkenes, and aromatic hydrocarbons.
