In the present work a new approach to modelling of the void fraction in the upward flow in the boundary layer is presented. The circulation around the bubble is modified to what has been previously assumed in the literature. The circulation is composed of two mechanisms which rotate in opposite directions. The resulting model predicts the wall peaking as well as the core peaking depending primarily on the bubble diameter. The proposed mechanism is entirely new in the available approaches. It is relatively general and enables future modifications.
