桨-舵间距对其组合系统水动力性能的影响
|
摘要
通过计算流体动力学(CFD)方法对敞水桨、桨-舵组合和优化间距的桨-舵组合装置进行数值仿真研究,分析桨-舵间距对其组合系统水动力性能的影响。螺旋桨敞水工况的计算值与物理模型试验值的吻合度良好,验证了数值计算方法的可行性。通过对比桨-舵间距大于推荐值的3个工况发现:在较低的进速系数下,系统的节能效率稍有增加,随着桨-舵间距的增大,节能效率呈现下降的趋势;在较高的进速系数下,随着桨-舵间距的增大,节能效率逐步下降。在较低的和中等的进速系数下,节能效率随着桨-舵间距的减小呈现逐步升高的趋势,在桨-舵间距减少10 mm时,组合体的节能效率最大可增加1.937%;在较高的进速系数下,节能效率随着桨-舵间距的减小有下降的趋势。
Numerical simulations about the hydrodynamic performance of propeller, combination system of propeller-rudder as well as the space optimized propeller-rudder system are carried out by computational fluid dynamics(CFD) method. It is found that the calculated results agree well with those from model test. Thus it verifies the feasibility of the proposed numerical calculation method in the case of propeller testing in open water situation.By comparing three kinds of operating conditions where propeller-rudder space is greater than the recommended value, it is found that the energy-saving efficiency of the composite system of propeller-rudder is slightly increased under low order coefficients. However, it begins to decreases with the increase of propeller-rudder space. At the same time, the energy-saving efficiency decreases gradually in higher order coefficient. If the propeller-rudder space decreases to a proper range, the energy efficiency gradually increases with the decrease of the propeller-rudder space in the case of lower and the middle order coefficients. When the propeller-rudder space is decreased by 10 mm, the energy efficiency of the combined system may be increased by 1.937%. However, the energy-saving efficiency decreases with decrease of propeller-rudder in the higher order coefficient.
