WebSep 25, 2015 · As can be seen from Fig. 4, the bubble separation efficiency increases along with the increase in Δ d due to bubble coalescence and break-up. The rate of increase of the efficiency gradually decreases, such that the separation efficiency eventually reaches near-stability. Table 1. GMR and separation efficiency results under different values of Δ d. WebMar 1, 2024 · The collision between bubbles and sidewall are handled by the hard-sphere model with a restitution coefficient of 1. The large eddy simulation (LES) is selected for turbulence. The simulation time is set to 180 s, of which the first 20s are discarded due to start-up effects. More detailed parameters are given in Table 1.

WebFeb 1, 2005 · The evolution of the flow within the pipe depends on a very complex interaction between bubble forces and bubble coalescence and break-up, e.g. the lift-force, which strongly influences the radial distribution of the bubbles, changes its sign depending on the bubble diameter. The consequence is the radial separation of small and large bubbles.
