The widely used Chen correlation, consisting of two parts, forced convection and nucleate boiling, was examined with the previously reported experimental data taken in both a flow-loop apparatus and a standard IC engine on subcooled flow boiling for a 50–50 ethylene glycol-water mixture. Comparisons between the Chen correlation and the flow-loop data suggested that a correction factor is required only on the forced convection component of the Chen correlation. The Chen correlation with the correction factor of 2.0 tolerably predicts the heat fluxes and the wall temperatures not only in the flow-loop apparatus but also in the coolant passages of the IC engine.
