Summary

A natural convection heat transfer experiment was conducted in mercury with gas injection in a vertical enclosure heated on one face at constant heat flux and cooled on the opposite face. Nitrogen gas bubbles were injected from a row of hypodermic tubes facing upwards along the bottom of the heated plate. A transverse magnetic field of magnitude from 0.07 to 0.50 T was imposed perpendicular to the heated surface. The range of the applied heat flux was between 370 and 16,000 watts/m2. Experimental results showed that for low heat flux rates, a small magnetic field intensity (about 0.07 T) significantly reduced the heat transfer coefficient in the presence of gas injection.
