What is it about?
This study extends a recently developed Eulerian framework for characterizing particle dispersion and erosion in impinging jets, where the framework can now handle bisectional systems. The Eulerian mass and momentum conservation equations are solved assuming a one-way coupling between the flow and the particles. Erosion at the eroded surface is computed using an empirical erosion model. The investigated flow configuration allows estimating the initial erosion for bisectional systems by first evaluating the initial erosion in the corresponding monosectional systems. Then, the erosion induced by particles from different sections is linearly added using a simplified calculator with different weights for each section. This calculator generates the initial erosion immediately and spares the need to run numerous expensive simulations for different bisectional systems. Analysis of the bisectional systems showed that intermediate erosion profiles are obtained when using different ratios between medium and large Stokes number particles. This numerical model offers a computationally efficient framework for CFD-based transient erosion calculation.

Why is it important?
The described calculator generates the initial erosion immediately and spares the need to run numerous expensive simulations for different bisectional systems. This numerical model offers a computationally efficient framework for CFD-based transient erosion calculation.
Perspectives
This work emphasizes the need to solve long-existing problems using new numerical tools that, even though they are somewhat less accurate than the commonly used practices for modeling particle erosion, can still yield accurate enough solutions at a fraction of the computational cost.
