| 摘 要： | 本文利用计算流体力学软件FLUENT对一小水线面双体船的粘性绕流进行了数值模拟，研究其船型与船舶阻力之间的关系，主要讨论以下几个方面：（1）特定船型条件下，随着雷诺数变化阻力的变化情况；（2）两潜体在相同长度不同间距时的阻力特性；（3）相同排水量的条件下，潜体不同长径比时的阻力特性。通过将数值模拟结果与经验公式比较，验证FLUENT软件用于船舶阻力分析的有效性和实用性。

| Abstract: | Numerical simulation of viscous flow around a full scale SWATH ship form is carried out by using the CFD software FLUENT, the relationship between SWATH ship models and resistance characteristics is researched, this paper focuses on the following aspects: (1)given SWATH ship model,to study the changes of resistance with changes of the Reynolds number;(2)to study the resistance characteristics under the condition that lengths of the two submersible models are the same but space between them changes;(3)given the same tonnage,to study the resistance characteristics with changes of aspect ratio of SWATH ship form.Based on comparing of numerical simulation result and experiential calculation result,it is proved that the software is effective and practically useful to analyze the resistance characteristics of SWATH ship. |
