数值拖曳水池与潜艇快速性CFD模拟研究

摘要

CFD simulation of submarine powering performance in the numerical towing tank of CSSRC is described in detail in this paper. The computation approach for resistance, flow field and hydrodynamic forces in open-water and self-propulsion (body-propulsor interaction) conditions are defined. Meanwhile, the various computation cases for submarine powering performance are analyzed. And the prediction accuracy is presented.These models consist of fifteen bodies of revolution (series models), ten submarine models of all appendages (series models), SUBOFF model, several submarine models and propeller models for method validation. The research result is an important component of numerical tank and can be adopted for the numerical simulation of flow around submarine in future.%详细介绍了中国船舶科学研究中心所建立的数值拖曳水池中的潜艇快速性CFD模拟研究.明确了潜艇阻力、流场、自航(艇/桨干扰)水动力以及螺旋桨敞水水动力的计算方法.同时对潜艇快速性算例进行了系统分析,详细给出了数值预报精度.这些算例的计算模型包含15条系列回转体模型、10条系列全附体潜艇模型、SUBOFF潜艇模型、多条供计算验证所用的潜艇模型和螺旋桨模型.文中的研究结果是数值水池的重要组成部分,可资今后潜艇绕流数值计算借鉴与采用.
