Numerical Simulation of Flow and Heat Transfer Characteristics in Biomass Feeder

In this paper, designed a swirling feeder for biomass tar, The numerical simulation of flow characteristics and temperature field heat transfer characteristics of the internal flow field was performed. Mixture multiphase flow model and Reynolds stress turbulence model are used, in the case of different feed flow ratios, Solved the internal flow field, concentration field and temperature field; Through research shows that when the flow ratio i = 0.6 ∼ 0.8, Biomass tar can enter the reactor through the feeder without causing coking.
