摘要:
為實現噴水推進船舶推力的快速預報,本文提出了一種通過求解興波阻力、粘性阻力和進流面物理參數實現噴水推進推力快速迭代求解計算的數值方法。本文依據船舶受力的平衡方程,在噴水推進流道內采用壓力躍變法,建立船舶噴水推進推力計算數學模型。采用邊界元法對興波勢進行求解,通過對船體加長處理,解決興波阻力計算中流道面元與自由液面面元互相穿透導致的影響系數矩陣異常等數值問題。運用湍流邊界層理論計算控制體進流面的速度、壓力和進流面邊界層影響系數。以三體船船模為研究對象,將數值計算結果與粘流計算流體力學噴水推進自航結果進行對比分析,結果表明:該方法預報三體船噴水推進系統推力相對誤差小于5%,能夠快速有效預報三體船噴水推進推力性能及推力減額,具有較強的理論研究和工程實際應用價值。
