Model & approach
- Calculate gas flow and representative particle classes in a coupled model
- Map impact locations, approach direction and near-wall loading indicators
Project study
Particle-based wear mapping in a hot-gas system
A multiphase assessment connected the flow field with particle paths and impact patterns to classify potential wear concentrations in a hot process-gas route.
Engineering question
Local abrasion could not be inferred from gas velocity alone because particle inertia, turning and wall interaction governed the load.
Boundary conditions
- Particle-laden hot-gas flow
- Project-specific particle, wall and operating assumptions
Results of the assessment
- Turns and secondary flow concentrated particles on specific wall regions.
- The maps distinguished highly exposed zones from regions with limited particle interaction.
Engineering consequence
Critical surfaces could be prioritized for protection, geometry revision or targeted material selection.
