الملخص EN

This paper addresses erosion prediction in 3-D, 90° elbow for two-phase (solid and liquid) turbulent flow with low volume fraction of copper.

For a range of particle sizes from 10 nm to 100 microns and particle volume fractions from 0.00 to 0.04, the simulations were performed for the velocity range of 5–20 m/s.

The 3-D governing differential equations were discretized using finite volume method.

The influences of size and concentration of micro- and nanoparticles, shear forces, and turbulence on erosion behavior of fluid flow were studied.

The model predictions are compared with the earlier studies and a good agreement is found.

The results indicate that the erosion rate is directly dependent on particles’ size and volume fraction as well as flow velocity.

It has been observed that the maximum pressure has direct relationship with the particle volume fraction and velocity but has a reverse relationship with the particle diameter.

It also has been noted that there is a threshold velocity as well as a threshold particle size, beyond which significant erosion effects kick in.

The average friction factor is independent of the particle size and volume fraction at a given fluid velocity but increases with the increase of inlet velocities.
