换热器管束排列角对流体力的影响研究
Study on Influence of Arrangement Angle of Tube Bundle on Fluid Forces in Heat Exchangers
摘要
Abstract
Fluid forces are influenced by arrangement angle with the bundle arrangement,which could make the flow field change.The flow field arrangement and fluid forces of tube arrays at normal arrange ment angle with cross flow are calculated by LES.The result shows that vortex shedding and turbulence are influenced by angle,especially at upstream.Fluid forces coefficients calculated with LES model agree well with those obtained with the experimental measurement.The results provide references and evidences for the analysis of flow induced vibration.关键词
