The levitation of a sphere by two parallel turbulent jets

Two vertical turbulent round jets are used to levitate a spherical particle. First, a symmetric configuration is investigated with the two jets of equal flow rates. A structure reminiscent of a pitchfork bifurcation is reported and characterized between a double trap configuration for low flow rates and a single trap regime at higher flow rates. A second configuration is then studied with the flow rates that differ between the left and right...
