摘要

B 系列螺旋桨的水动力性能可通过计算 MARIN 公布的多项式方程来确定。此外，还可以通过改变桨叶的外倾角比来分析和评估 B 系列螺旋桨的改型。外倾角比会影响螺旋桨箔片上的升力，直接影响螺旋桨的推力和扭矩。计算流体动力学（CFD）基于雷诺平均纳维-斯托克斯方程（RANSE）和显式代数应力模型（EASM）形式的湍流模型进行了数值计算。研究的总体结果表明，与外倾率为 0% 的箔片相比，外倾率为 2.2% 的箔片的效率提高了 4.182%。

Hydrodynamic Performance Analysis of Camber Ratio Variations on B-series Propeller Types

The hydrodynamic performance of the B-series propeller can be determined by calculating the polynomial equation published by MARIN. Furthermore, analysis and evaluation of B-series propeller modifications can be done by varying the camber ratio of the foil. The camber ratio affects the lift force on the propeller foil, directly affecting the propeller thrust and torque. Numerical calculations were carried out using Computational Fluids Dynamics (CFD), based on Reynolds Averaged Navier Stokes Equations (RANSE) and turbulence model in the form of explicit algebraic stress models (EASM). The overall results of this study show an increase in efficiency of 4.182 on the foil with a camber ratio of 2.2% when compared to the foil camber ratio of 0%.
