Abstract

The theoretical analysis of the erosion effects due to a jet of hot liquid impinging obliquely onto a solid structure is very complex because the geometry is fully 3 D, two materials in two different phases are involved and the geometry of the eroded surface is continually changing. In principle a complete set of NavierStokes equations with initial and boundary conditions could be used to analyse such a problem, but this would be computationally prohibitive. A more simplified model has been realized where three different domains are defined and solved separately, that is, the spreading jet, the boundary layer, and the solid structure. The paper not only describes the numerical procedures used to investigate the erosion process but it also compares the computer code predictions against data from KfK, Karlsruhe for an experiment in which a molten jet formed from a thermite reaction falls onto a steel plate.
