The paper provides insight into the local and instantaneous turbulence modification induced by small spherical bubbles in an upward directed turbulent channel flow. This is accomplished by analyzing each term of the transport equation of the local and instantaneous kinetic energy for bubbly flows and dedicated flow visualizations are provided to address the mechanisms involved in the turbulence modification.
