弯道中环流对船舶产生的倾覆力矩计算分析
Study and Calculations of Capsizing Moment of Circumfluence on Ships in Curving Channels
【摘要】 结合水力学知识,研究了弯道中水流的环流形成机理,给出了弯道中的横向自由水面表达式。通过环流垂向的速度分布公式,探讨了弯道中航行的船舶的受力情况,并计算出了环流对船舶产生的力矩作用的大小,给出了计算表达式。
【Abstract】 Combining the knowledge of hydraulics,the reason of formation of the circumfluence is studied and the equation of free water level in curving channels is given.By studying the equation of vertical velocity distribution,the force and moment on ships from the circumfluence is studied and the equation is offered.
