[en] The objective of this work is to analyze particle-induced erosion within a nozzle for abrasive water jet
cutting, through a Euler-Lagrange approach. In an abrasive water jet cutting device a high-speed water jet
is used to accelerate abrasive particles forming a turbulent mixture of water, entrained air and abrasive
powders traveling at hundreds of meters per second. The focusing tube represents a key component, whose
primary scope is to focus and stabilize the flow forming in the mixing chamber, in order to ensure optimal
cutting performances of the device. Nevertheless, this nozzle often happens to be the first target of the
erosive action of the flow. This phenomenon significantly shortens the operational life of a nozzle. The
numerical approach proposed in this work aims to provide an insight to this very fast and disruptive
phenomena that are difficult and expensive to be captured by purely experimental studies.
