Abstract EN
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 inlet temperature, and erosion reduced thickness are examined.
The presence of erosion pit brings about the obvious fluctuation of temperature drop along the extrados of bend.
And the minimum temperature drop presents at the most severe erosion point.
Small inlet temperature or large inlet velocity can lead to small temperature drop, while shallow erosion pit causes great temperature drop.
The dimensionless minimum temperature drop is analyzed and the fitting formula is obtained.
Using the formula we can calculate the erosion reduced thickness, which is only needed to monitor the outer surface temperature of bend pipe.
This new method can provide useful guidance for pipeline monitoring and replacement.
