本发明提供一种船舶引水口截面积控制方法及装置,该船舶引水口截面积控制方法包括:获取船舶航行时的第一速度挡位;基于第一速度挡位和第一表格,确定引水口结构的目标截面积,其中,第一表格包括引水口结构的多个截面积以及船舶的多个速度挡位;将引水口结构的截面积调整为目标截面积。本发明方法能够使船舶在不同速度挡位航行时均能确定最优的引水口截面积,降低了引水口内水流的拖曳阻力对水流量的影响,进而满足船舶在不同航速下的整体冷却需求。
The invention provides a ship diversion port sectional area control method and device. The ship diversion port sectional area control method comprises the steps of obtaining a first speed gear when a ship sails; based on the first speed gear and a first table, the target sectional area of the water diversion port structure is determined, and the first table comprises a plurality of sectional areas of the water diversion port structure and a plurality of speed gears of the ship; and adjusting the sectional area of the water diversion port structure to the target sectional area. According to the method, the optimal sectional area of the water diversion port can be determined when the ship sails at different speed gears, the influence of dragging resistance of water flow in the water diversion port on the water flow is reduced, and then the overall cooling requirement of the ship at different navigational speeds is met.
