Highlights

• Dense particle transport within cyclone separator was modeled by hybrid Euler–Lagrange approach.

• The influences of several submodel parameters on the calculated results were investigated.

• Qualitative links were showed between the numerical and experimental data.

• The turbulence effects inside the separator were modeled using the Reynolds stress model.

Abstract

This paper presents a numerical simulation of the flow inside a cyclone separator at high particle loads. The gas and gas–particle flows were analyzed using a commercial computational fluid dynamics code. The turbulence effects inside the separator were modeled using the Reynolds stress model. The two phase gas–solid particles flow was modeled using a hybrid Euler–Lagrange approach, which accounts for the four-way coupling between phases. The simulations were performed for three inlet velocities of the gaseous phase and several cyclone mass particle loadings. Moreover, the influences of several submodel parameters on the calculated results were investigated. The obtained results were compared against experimental data collected at the in-house experimental rig. The cyclone pressure drop evaluated numerically underpredicts the measured values. The possible reason of this discrepancies was disused.
