摘要
通过数值模拟,并结合工程实际,应用正交设计法对掺气坎体型参数进行了空腔特性的敏感性分析,通过极差与方差分析得出了各参数对外空腔长度、内空腔长度等空腔特性的影响效应及权重大小。为掺气坎的体型设计提供了一定的理论依据,在工程实际中具有较强的应用参考价值。
Shape parameters of bottom aerator adopted by an actual project are analyzed for its cavity properties with numerical simulation based on an orthogonal design method.The weight coefficients of all influencing factors,near-wall cavity length and middle cavity length,etc.,are calculated by range and variance analysis.The results provide a theoretical foundation and a reference for shape design of aerator.
