Parallel grooves were made on a copper surface with widths ranging from 0.2 mm to 0.5 mm at intervals of 0.1 mm. The inclination angle of the grooves to the horizontal was set at 30° and 60°, and the depth of the microchannel grooves was 0.3 mm. The achieved heat flux ranged from 25 kW/m>² to 1730 kW/m², and the heat transfer coefficients ranged from 12 kW/(m²K) to 475 kW/(m²K). The influence of geometric parameters such as width, inclination angle of the microchannel, surface ex-tension, and Bond number on heat exchange efficiency was examined. A nearly sixfold increase in α (heat transfer coeffi-cient) and a twofold increase in critical heat flux were observed compared to a smooth surface.}, type={Article}, title={Pool boiling for water on surfaces with inclined microchannel}, URL={http://www.journals.pan.pl/Content/131563/4_AoT_659_2023_Kaniowski.pdf}, doi={10.24425/ather.2024.150850}, keywords={Pool boiling, Inclined microchannel, Heat transfer coefficient, Critical heat flux}, }
