The metal foam used for filling a heat exchanger channel can effectively improve two-phase heat transfer performance and has good application prospects. Accurate prediction of the two-phase pressure drops in the metal foam channel is required for equipment and system designs in engineering applications. It is necessary to develop a suitable method for predicting the two-phase pressure drop in metal foam channels under a wide range of conditions. The two-phase pressure drop experimental data in the metal foam channels of six references were used. The experimental conditions included metal foam pores per inch (PPI) of 5–40

porosity of 0.87–95

channel hydraulic diameter of 4.36–13.8 mm

mass flux of 0–350 kg/（m2·s）

and quality of 0–0.8. The distribution of the two-phase multiplier and the Lockhart-Martinelli parameter was analyzed

and it was found that the two-phase multiplier increased with a decrease in the ratio of the metal foam pore diameter to the channel hydraulic diameter and increased with an increase in the quality; when the diameter ratio changes from 0.31 to 0179

the two-phase multiplier increases by 1.37 to 1.52; and when the quality changes from 0 to 0.8

the two-phase multiplier increases by a factor of 3.41. A new correlation was developed based on the Lockhart-Martinelli correlation. The results show that the absolute average error between the predicted values and experimental data is 22%

which indicates that the new correlation can provide an accurate prediction.
