根据挖泥船排泥管内流体流动状态的微分方程描述 ,用相似转换法推导出了各相似准数 ,并且分析了它们在模型与原型的相似关系中的主次地位 ,得出了模型与原型的阻力相似是最主要的结论 .
According to the description of the differential equation of fluid flow in the dredger’s mud pipe, the similarity criteria are deduced by the similarity conversion method, and their primary and secondary positions in the similarity relation between the model and the prototype are analyzed. Finally, Similar resistance is the most important conclusion.
