摘要
Dust or sand heavy environments cause many problems for the aircraft industry due to the impact of fine particles upon equipment lifespan. We created a CFD model and conducted the numerical simulations needed to determine the distribution of a granular secondary phase within a multiphase flow using the Eulerian Model. The flow consists of sand or dust laden hot air, used in a harsh environment testing facility. The numerical study, performed with specialized CFD software, aims at determining the efficiency of the existing injection system in regards to secondary phase concentration and distribution within a test section of the harsh environment testing facility. Results obtained using an axisymmetric model of the facility indicate that improvements can be made to the injection system to augment the secondary phase distribution. Improvements to the above testing facility increase the accuracy of the experiments carried therein, serving in turn to benefit the aeronautical industry.
