摘要：

The paper presents the results of an experimental study of the effect of 3D capillary-porous copper coatings with various geometries on the heat transfer rate and bubble dynamics during water pool boiling. The surfaces were modified via additive manufacturing (3D printing). It is shown that for the fabricated surfaces, the heat transfer enhancement is up to 2 times as compared with the reference bare surface. The highest degrees of the heat transfer enhancement are achieved for the coatings with the smallest wavelength of the structure modulation and channel width. High-speed video recording of boiling was also carried out, based on which the bubble departure diameters were analyzed for surfaces of various types.
