We invite you all to check out the new article published by NUEM – Multiphase Flow Research Center in the International Journal of Multiphase Flow, “Experimental Study on the Behavior of Single Rising Bubbles in a Confined Rectangular Channel”. In this work, the influence of the walls on the dynamics of single bubbles rising through thin vertical channels was experimentally investigated by using the shadowgraph technique. The influence of the confinement on the velocity, deformation and frequency of the oscillation of the bubbles was analyzed. Correlations to predict the velocity and drag coefficient of the bubbles as a function of the confinement parameter were proposed.
