Numerical Simulation of Blast Nozzles

This paper describes the development of a CFD model for simulating blast nozzles in the OpenFOAM environment and quantifies the performance of two #6 blasting nozzle geometries operating with garnet. Simulation results indicate that the developed CFD model is suitable for blast nozzles operating with #80 garnet or finer.

In recent decades, lower density blasting media, such as garnet has become widely used. This has been in conjunction with existing blast nozzles, which are of a simple, un-optimised geometry. One means to design a more efficient blast nozzle is through the use of computational fluid dynamics (CFD) in conjunction with automated optimisation. This paper describes the development of a CFD model for simulating blast nozzles in the OpenFOAM environment and quantifies the performance of two #6 blasting nozzle geometries operating with garnet. Simulation results indicate that the developed CFD model is suitable for blast nozzles operating with #80 garnet or finer.
