“…The results indicate that, for single-phase flow, the 20-PPI, 30-PPI and 60 PPI metal foam increase the heat transfer coefficient by up to 3.5, 4 and 5.1times, respectively, and increase the pressure drop by up to 3.2, 3.8 and 5.7 times, respectively, compared with the empty channel[150]. As for the flow evaporation[151], the heat transfer was enhanced in all cases by the fitted metal foams, but the heat transfer enhancement effect of metal foam was found to be inversely related to the pore density.…”

“…The commercial usage of metallic foams was available in the early 1980s and has wide applications such as in transportation, infrastructure and construction, automotive, aerospace, and military equipment (Nawaz et al, 2012;Liu et al, 2014). Research and development in metallic foam includes utilization in thermal applications, such as in heat exchanger equipment (Abadi et al, 2016), heat sinks in electronics (Hu et al, 2016), engine combustion, aircraft, and automotive systems (Shirzadi et al, 2008). There is a growing demand in metal foam, with a USD 82.0 million share in the global market (Grand View Research, 2017).…”

Utilization of open-cell metal foams in functional applications such as in energy absorption, noise absorber, heat insulator, and lightweight panels is trending in many industrial applications. The development of reliable joining technologies for sandwiched metal foams is crucial for thermal application and one of the techniques used is brazing process. In the current work, copper foam was sandwiched between a copper plate using amorphous filler of Cu-9.7Sn-5.7Ni-7.0P (Cu: copper, Sn: tin, Ni: nickel, and P: phosphorus) via brazing technique. The shear test was conducted on the brazed joint interface of copper/copper foam, while the compressive test was carried out on the brazed sample. Microstructures of the copper substrate surface obtained from the shear fracture of brazed copper/copper foam show the tear region and cleavage fractures. The stress–strain curve of shear and compressive strength explains the deformation behavior of the brazed sample.

“…The thermal performance of the heat exchanger can be improved by using metal foam inserts with a high surface area to volume ratio (790-2740 m 2 /m 3 ) and high porosity (>90%). Several groups have published experimental research on metal foam heat exchangers [1][2][3][4][5][6], and, to date, many studies have been conducted on the convective heat transfer of single-phase liquids or gases using small heat exchangers and metal foams [7][8][9][10][11][12][13][14][15][16][17][18][19].…”

Heat transfer under flow boiling is better in a rectangular channel filled with open-cell metal foam than in an empty channel, but the high pressure drop is a drawback of the empty channel method. In this study, various types of metal foam insert configurations were tested to reduce the pressure drop while maintaining high heat transfer. Specifically, we measured the boiling heat transfer and pressure drop of a two-phase vertical upward flow of R245fa inside a channel. To measure the pressure and temperature differences of the metal foam, differential pressure transducers and T-type thermocouples were used at both ends of the test section. While the saturation pressure was kept constant at 5.9 bar, the steam quality at the inlet of the test section was changed from 0.05 to 0.99. The channel height, moreover, was 3 mm, and the mass flux ranged from 133 to 300 kg/m2s. The two-phase flow characteristics were observed through a high-speed visualization experiment. Heat transfer tended to increase with the mean vapor quality, and, as expected, the fully filled metal foam channel offered the highest thermal performance. The streamwise insert pattern model had the lowest heat transfer at a low mass flux. However, at a higher mass flux, the three different insert models presented almost the same heat transfer coefficients. We found that the streamwise pattern model had a very low pressure drop compared to that of the spanwise pattern models. The goodness factors of the flow area and the core volume of the streamwise patterned model were higher than those of the full-filled metal foam channel.
