Modeling the Thermal Conductivity of Ionic Liquids and Ionanofluids Based on a Group Method of Data Handling and Modified Maxwell Model

The objective of this study is to
develop a model to determine
the thermal conductivity of pure ionic liquids and ionanofluids. In
order to estimate the thermal conductivity of pure ionic liquids,
a group method of data handling model is proposed based on 23 ionic
liquids corresponding to 216 experimental data points. The average
absolute relative deviation for all studied systems was 1.79%, which
is a satisfactory degree of accuracy for the proposed model. Furthermore,
the Maxwell model is modified to correlate the thermal conductivity
of ionanofluids as a function of temperature and volume fraction of
nanoparticles. The average absolute relative deviation for this model
is 0.61%. Additionally, Maxwell and modified geometric mean (mGM)
models are used to evaluate the models that predict the thermal conductivity
of ionanofluids. The results show that mGM is more accurate for prediction
of thermal conductivity of ionanofluids.
