ABSTRACT:
A dynamic containment vessel defined by a stable fluid recirculation within a generally cylindrical containment region. The dynamic vessel is maintained by fluid momentum which establish superposed line and ring vortices within the containment region. Particles entrained within the containment vessel are retained until reduced to a preselected particle size and discharged along the axis of the vessel. Fluid injection nozzles are positioned at least at the discharge end of the vessel, at the perimeter of the containment region, and are oriented to inject gas into the containment region with a momentum having a component tangential to the cylindrical containment region and a component parallel to the longitudinal axis of the cylindrical containment region. The entrained particles may be a fuel, in which case the containment vessel may serve as a combustor.
