How and up to what extent can the alteration in a surface caused by eroding particles affect the flow and/or erosion in subsequent time-steps? These are the questions that the current work seeks to address. For this purpose, a pseudo-transient 3D Com

A new dimensionless number for erosion prediction in standard elbows under gas-liquid-solid flow conditions is developed. For this purpose, a machine learning algorithm is trained and used to generate erosion data. Then, three important dimensionless

A 2-D Computational Fluid Dynamics (CFD) model was used to investigate erosion in standard elbows (r/D = 1.5) under different flow and particle conditions. Afterwards, dimensional analysis was performed to first obtain the governing dimensionless gro

Huge waves are periodic interfacial structures which are observed in vertical co-current gas-liquid two-phase flow under churn and the transition between churn and annular flows. Published data examining vertical gas-liquid flow indicate that a huge

Gas-liquid annular flow is commonly observed in natural gas transmission and offshore horizontal pipelines. The presence of sand particles in such flows can cause severe equipment degradation of piping elements. The most vulnerable parts of pipeline

Intermittent two-phase flows are commonly encountered in the petroleum industry. Much attention has been focused by several researchers on intermittent flows existing at low superficial gas velocities ( From the void-fraction time series data, the pe

Oil and gas production and transportation facilities have the potential of catastrophic explosions, fire and release of toxic gases due to erosion failures which may lead to loss of lives and properties. Repairs of such a complex system can be very e

Particulate gas-liquid upward annular flow can be often observed in the oil and gas industry during production. This type of flow, of course, can be very erosive, as it is associated with high gas flow rates. Despite the interest due to this potentia

Although erosion under multiphase flow conditions can be observed frequently, due to its inherent complex nature, it has received much less attention compared to that in single phase flow. In the present study, a Computational Fluid Dynamics (CFD) mo

Slug flow, which commonly occurs in the petroleum industry, is not always a desired flow pattern due to production operation problems it may cause in pipelines and processing facilities. To mitigate these problems, flow conditioning devices such as m
