Numerical Investigation of Temperature Distribution in an Eroded Bend Pipe and Prediction of Erosion Reduced Thickness
Accurate prediction of erosion thickness is essential for pipe engineering. The objective of the present paper is to study the temperature distribution in an eroded bend pipe and find a new method to predict the erosion reduced thickness. Computational fluid dynamic (CFD) simulations with FLUENT software are carried out to investigate the temperature field. And effects of oil inlet rate, oil in...
متن کاملVisualization of Swirling Gas-solid Flow Pattern in a Horizontal Pipe Based on Wavelet Analysis of Pressure Signals
The wavelet transform is applied to experimental pressure fluctuations in swirling gas-particle two-phase flows in this paper, to identify and interpret flow pattern transitions in both Fourier and physical spaces. From randomlike pressure fluctuations the characteristic of swirling gas-particle twophase flows can be extracted, and the relationship between the wall pressure fluctuation and the ...
متن کاملNumerical Simulation of Semi-Elliptical Axial Crack in Pipe Bend Using XFEM
In this work, XFEM is employed to obtain the stress intensity factors (SIFs) of a semi elliptical part through thickness axial crack. In XFEM, additional functions are employed to enrich the displacement approximation using partition of unity approach. Level set functions are approximated using higher order shape functions in the crack front elements to ensure the accurate modeling of the crack...
متن کاملNumerical Study Scour Pattern on Channel Bend Using Flow-3D Software
In nature, a direct route to the river is uncommon. Most rivers have channels that bend wherea complex scour pattern dominates. We have intended to study the behavior patterns necessary to scour a river known as the dominant bends. Numerical models are powerful instruments for the prediction of such areas and can provide a good understanding of these areas. In the present study we have used a t...
متن کاملAnalysis of pressure fluctuations in swirling turbulent flows
Turbulent flows display intermittent pressure drops associated with vorticity concentrations. Using wavelet transform, we characterize these low pressure events and study some of their statistical characteristics in a flow generated between the
