Characteristics of magnetohydrodynamic bubbly jet

POSTER

Abstract

Pattern formation and bubble size of magnetohydrodynamic (MHD) bubbly jet driven by the Lorentz force is presented experimentally. The Lorentz force generated by perpendicularly placed magnetic field and electric field displacing conductive saltwater, chemically produced gases (hydrogen, oxygen and chlorine) forms a typical two-phase MHD jet flows. Taking advantage of the bright gases, the emergence of bubbly jet and bubbles are analyzed. Based on the control parameters, such as magnetic field strength, input current strength, geometry of the experimental apparatus, and fluid properties, a Lorentz-force based Reynolds number $Re_L$ is used to categorize the flow regimes and size distributions of bubbles.
