Experimental measurements were performed with and without the injection of $\\sim 2.5$ mm diameter bubbles (corresponding to $Re_b \\approx 600$) in a rectangular water column heated from one side and cooled from the other. The gas volume fraction $\\alpha$ was varied in the range $0\\% - 5\\%$, and the Rayleigh number $Ra_H$ in the range $4.0 \\times 10^9 - 1.2 \\times 10^{11}$. We find that the global heat transfer is enhanced up to 20 times due to bubble injection.
