| 摘 要： | 研究了螺旋桨诱导的船体表面脉动压力试验预报值随空气含量变化的规律及螺旋桨模型空泡形态随含气量变化的规律,并与实桨空泡对比分析;探索了脉动压力试验预报与实桨测量值最接近的空气含量控制准则;比较了螺旋桨模型在船模伴流场和修正后的伴流场中工作时,螺旋桨诱导的船体表面脉动压力预报值及螺旋桨模型空泡形态,与实船测量观察结果进行对比,并就伴流场修正对螺旋桨诱导的船体表面脉动压力试验预报的影响作了探讨;研究了螺旋桨诱导的船体表面脉动压力的预报值随桨模试验转速变化的规律。

| Abstract: | To improve Lab prediction of propeller induced pressure fluctuation,three of the main influence factors are studied in the SSSRI cavitation tunnel.The law of variation of propeller-induced ship hull pressure fluctuation due to different tunnel gas contents is studied.The law of propeller model cavitation pattern variation is also observed at different gas contents,compared with that of its corresponding full-scale propeller.The norm of tunnel gas content is explored to fit the experimental prediction with i... |
