用于船舶设计的全尺寸 CFD 仿真:米洛万·佩里奇述评
计算流体力学 (CFD) 在船舶设计中应用广泛。CFD 通常在模型级别运行,以便与试验槽验证数据进行比较。但是,由于无法观察到雷诺数的缩放,因此很难将模型尺寸结果转换为全尺寸结果。这意味着模型尺寸的理想设计通常不符合全尺寸的要求。在模型尺寸上,研究不同比例的船舶组件(例如,船体-螺旋桨相互作用或节能装置)之间的相互作用也并非易事。
在本白皮书中,米洛万·佩里奇 (Milovan Peric) 教授探讨了针对运行全尺寸 CFD 仿真的一些常见保留意见,并鼓励在实际操作条件下对船舶设计进行全尺寸分析。文中研究了雷诺数缩放的影响,以及计算网格要求,同时列举了在复杂情况下进行全尺寸 CFD 仿真的示例。在很多情况下,全尺寸仿真都比其他备选方案更加准确而可靠,因而也更有助于理解设计性能。
Scale analysis examples
The author examines scale analysis examples such as the effects of Reynolds number scaling, as well as computational mesh requirements, and shows examples of full-scale CFD simulation on complex cases. In many cases, full-scale simulation is more accurate and reliable than alternatives and leads to a greater understanding of design performance.
Analysis and design of marine structures
Full-scale analysis and design of marine structures and complete systems require digital twin technology. With robust software, simulation can be performed to mirror realistic operating conditions to ensure proper design is found. Many experienced users in the industry successfully apply CFD simulations with full-scale, read more from this review to learn the benefits of full-scale CFD.
Scale prediction software
Use cases of full-scale prediction software, and much more, can be found in this marine industry resource. In many cases, full-scale prediction is more reliable than scaling up model experiments.
