Sand/dust test is one of the key projects to examine the environmental adaptability of ordnance equipment.In order to decrease the abrasion of test facility caused by the sand/dust particles,the particles contained in the airflowneed to be reclaimed effectively.Amathematical model of Useparator is established.The flowfield and the trajectories of particles inside the separator are obtained using a numerical simulation method,and the separation efficiency and pressure drop of separator with different rows of separate components are also obtained at various flowvelocities.The simulation results indicate that the efficiency of U inertia separator is affected by the flowvelocity evidently,and a reasonably designed separator can meet the requirement of the separation efficiency in particular situation.The results can be use as reference for the design and test of sand/dust separate systems.
Sand/dust test is one of the key projects to examine the environmental adaptability of ordnance equipment. In or- der to decrease the abrasion of test facility caused by the sand/dust particles, the particles contained in the airflow need to be reclaimed effectively. A mathematical model of U separator is established. The flow field and the trajectories of particles inside the separator are obtained using a numerical simulation method, and the separation efficiency and pressure drop of separator with different rows of separate components are also obtained at various flow velocities. The simulation results indi- cate that the efficiency of U inertia separator is affected by the flow velocity evidently, and a reasonably designed separator can meet the requirement of the separation efficiency in particular situation. The results can be use as reference for the design and test of sand/dust separate systems.
