EFFECT OF HEAT TRANSFER ON MULTIPHASE FLOW THROUGH AXIAL CYCLONE SEPARATORS: A NUMERICAL STUDY
RESUMO
A numerical study of gas-solid flow through an axial cyclone separator is carried out by Eulerian-Lagrangian CFD approach, by solving the incompressible turbulent Navier-Stokes equations with RNG-k ε model and discrete phase modelling (DPM) of particles. The effective filtration of inlet air from dust particles is important for prolonged engine life cycle. In axial separators, a helical swirl generator is used for imparting swirling motion to the particle laden flow and particles are filtered by centrifugal separation and then scavenged using a vortex tube. The effects of heat transfer on the fluid and solid phase are analysed using an opensource CFD package OpenFOAM. The study focuses on how the velocity field, pressure drop and filtration efficiency are affected by the variation of temperature of inlet air.
