Abstract: To investigate the influence of pore density and grooved dimension on the operating mechanism of metallic nickel foam evaporators at the microscale, flow boiling heat transfer experiments were conducted using twelve samples with three pore densities(100, 500, and 1 000 mesh)and four grooved dimensions(0, 0.4, 0.7, and 1.0 mm). The heat flux density, convective heat transfer coefficient and pressure drop were calculated and analysed. The results showed that, for samples with the same pore density, the grooved dimension of 0.7 mm yielded the highest convective heat transfer coefficient. Under identical grooved dimension, the optimal performance was achieved by the sample with the pore density of 500 mesh and the groove dimension of 0.7 mm, which convective heat transfer coefficient increased by 3.02 times compared with the 100 mesh sample, reaching a maximum critical heat flux of 152.40 W/cm2 and a peak convective heat transfer coefficient of 27 630.50 W/(m2·K). Surface modification of metallic nickel foam with silica sol was further carried out to examine the effect of wettability on heat transfer. The results indicated that the combination of grooving and hydrophilic modification did not exhibit a synergistic effect. Without grooves, hydrophilic modification enhanced heat transfer performance. However, it also significantly weakened the improvement brought by grooving, resulting in lower performance compared with untreated metallic nickel foam samples.

Key words: metallic nickel foam, pore density, grooved dimension, flow boiling heat transfer, mechanically pumped two-phase loop
