1 LINFLOW 1.41 Pipe fluid-elastics. Fluid dynamics: Water flow U= 5 m/s Structure L=0.238 m Out. Dia.= m Inn. Dia.= m E=110E9 Pa Dens=4500 kg/m3 Constr.:Walls at both ends Fluid-elasticity of a fluid-conveying pipe

2 LINFLOW 1.42 The ANSYS first and second modal frequency are 1319 Hz Structural Results for Pipe used in a Fluid- Elastics Analysis. The ANSYS Structure dynamics The first structural modeThe second structural mode (Click on Picture for Animation)

3 LINFLOW 1.43 LINFLOW predicts a 1.st fluid-elastic mode with a frequency of Hz The analytical result is Hz (Δ 0.6%) LINFLOW Fluid-Elastics Analysis of Pipe with Flow. Coupled Fluid-elastic mode (Click on Picture for Animation)
