小水线面三体船与细长型三体船剩余阻力对比分析
|
摘要
[目的]为研究潜体横剖面为圆形的小水线面三体船(TriSWACH)侧体布局位置对剩余阻力的影响,以及其与细长型三体船剩余阻力的对比,[方法]在已验证CFD基础上,通过CFD方案下的剩余阻力系数,并与同排水量、工况下的细长型三体船剩余阻力系数试验值进行比较。[结果]结果表明,在全航速区间,潜体横剖面为圆形的小水线面三体船的剩余阻力系数普遍小于相同排水量细长型三体船的剩余阻力系数;TriSWACH在最佳航速区间Fr=0.338～0.494时减阻效果最好,此时,侧体位于主体后部时可获得17.95%的最大减阻。[结论]该研究具有一定的工程借鉴意义。
[Objectives]To study the effect of side-hull layouts of Trimaran Small Waterplane Area Center Hull(TriSWACH)with circular transverse section on residual resistance and compare its residual resistance with that of slender trimaran.[Methods]The CFD numerical forecast of viscous flow field around TriSWACH has been verified to be reliable and viable,so we use the CFD method to numerically simulate the viscous flow field around TriSWACH with circular transverse section,calculate the residual resistance coefficient under different speeds and side-hull layouts, and then compare with the experimental values of residual resistance coefficient of slender trimaran with the same displacement and working conditions.[Results]The results show that the residual resistance coefficient of TriSWACH is generally smaller than that of slender trimaran at full speed;TriSWACH has the least resistance in the optimal speed range Fr=0.338-0.494,and the resistance is maximally reduced by 17.95% when side-hull are at the rear part of main hull.[Conclusions]This study can be used for reference in engineering.
