The swirl flow could enhance the turbulent mixing and promote the slagging in the entrained flow gasifier. In recent research, the effect of swirl flow on cold flow characteristic of entrained flow gasifier was neglected or simplified. To address this, a three-dimensional computational fluid dynamic (CFD) simulation was presented to investigate the effect of swirl flow on the cold flow characteristic of entrained flow gasifier. Several control parameters, i.e., the diameter and injection velocity of nozzles, were found to significantly affect swirl intensity and velocity distribution in the entrained flow gasifier. Our numerical simulation provides an effective way for researchers or engineers to optimize and scale up the gasifier and nozzle.
