摘要
基于CFD方法,结合标准k-ε湍流模型,利用非定常滑移网格方法预报敞水螺旋桨和桨舵干扰的水动力性能。通过计算得出不同进速下螺旋桨和舵的推力曲线,并进行比较,从中找出一定的规律;同时给出舵表面的压力分布图、桨舵干扰情况下的尾涡图和敞水情况下舵的尾涡图。结果表明,在有舵干扰时螺旋桨在均匀来流情况下产生的推力呈周期性分布,桨舵之间的干扰随进速的增加而逐渐增大。
CFD method combined with standard turbulent model and moving mesh was used to study the interaction between the propeller and rudder. The force curve of the propeller and rudder in different advance coefficient by calculation was obtained and the regulations from them were also obtained. The pressure distribution on the rudder, the wake after rudder with propeller and without propeller was presented. Results showed that the force of propeller and rudder all periodically fluctuated and the interac-tion between the propeller and rudder increased as the advance coefficient increased.
