Interaction and influence of a flow field and particleboard particles in an airflow forming machine with a coupled Euler-DPM model.

Particleboards are widely used in the artificial board market, which can be constructed from a variety of raw materials and require small amounts of energy to be produced. In the particleboard production process, forming machines play an important role as the key equipment for achieving continuous p...
