Experimental study of submerged liquid metal jet in a rectangular duct in a transverse magnetic field

A liquid metal flow in the form of a submerged round jet entering square duct presence transverse magnetic field is studied experimentally. range high Reynolds and Hartmann numbers considered. Flow velocity measured using electric potential difference probes. detailed study duct's cross-section about seven jet's diameters downstream inlet reveals dynamics, which unsteady dominated by high-amplitude fluctuations resulting from instability jet. The structure fluctuation properties are largely determined value Stuart number ${{N}}$ . At moderate , mean profile retains central with three-dimensional perturbations increasingly suppressed as grows. higher values becomes quasi-two-dimensional acquires an asymmetric macrovortex, reemerging.
