| 摘 要： | 采用了理论计算和试验的方法,就渔政船各航速下船体阻力进行了计算和船模试验验证。对船体阻力计算结果的压阻力、黏性阻力进行了剥离、分析,与模型试验中获得的剩余阻力等各成分进行了比较和分析。研究表明在湍流黏性理论下计算得到的船模黏性阻力与相应的摩擦阻力相近;层流黏性理论比湍流理论计算耗时短,各速度点的船体压阻力相近;高航速工况下黏性理论计算的船体压阻力与船模试验得到的船体剩余阻力基本一致。基于上述分析,该文对实船阻力预报方法进行了进一步的探讨。

| Abstract: | The theoretical and experimental methods are adopted here to calculate the resistance of a fishery ship under various speeds.Components of total resistance are analyzed separately and compared with the counter parts from model experiments.Research shows that viscosity resistance calculated based on turbulence theory is close to the friction resistance.Using laminar model can obtain approximative pressure resistance while it consumes less computation time comparing with that of turbulence model.The pressure ... |
