摘要

A simple correlation function for the thermal conductivity of liquid methane has been obtained. The correlation has then been extended to other light alkans such as ethane, propane and iso-butane by introducing four adjustable parameters, which are fluid dependent. The obtained correlation is applicable in the temperature range 200-400 K and the pressure range 5-20 MPa. The mean relative errors for the calculated thermal conductivities are rarely greater than 3% for all cases.
