【摘要】 根据弗洛德准则设计1:1、1:10,1:20…1:100共11种不同比尺的平台模型,确定相应的风速,利用Fluent模拟计算不同比尺下作用于平台模型上的风荷栽,得到不同雷诺数条件下的试验结果,获得弗洛德准则设计平台结构模型试验的雷诺数效应。结果表明,海洋平台风荷栽模型试验的雷诺数效应随模型比尺的增大而变小,模型比尺较小时.模型试验所得成荷栽比实际风荷栽大。更多还原

【Abstract】 Based on Froude simulate rule, the 11 different scale platforms are designed and the matching speed can be acquired. The Fluent software is used to calculate the wind loads on these models, and then the Reynolds number effect on the wind load in model tests of offshore platform can be obtained. The results show that the Reynolds number effect increases with the scale reduction. The wind load by a smaller scale model test is larger than the prototype wind load.更多还原
