New correlation accurately predicts thermal conductivity of liquid paraffin hydrocarbons

摘要

Knowledge of the thermal conductivity of the fluids involved is an essential for the prediction of the rate of heat transfer in all heat exchangers. Therefore, in this paper a simple to use correlation is developed to accurately predict the thermal conductivity of liquid paraffin hydrocarbons as a function of temperature and molecular weight. The proposed correlation has very good agreement with the reported available data, and the average absolute deviation percentage between the observed values and calculated results is 1·44%.
