Abstract:

History effect will occur when bubble surface concentration changes during the mass transfer between bubble and ambient liquid. In order to estimate the history effect in bubble diffusion process, the project uses numerical simulation to study the significance of history effect in three situations: (1)determine pressure oscillation threshold in rectified diffusion (2)change lifetime of dissolution and growth for a single component bubble in ambient liquid, when surface tension is non-negligible (3) change the dissolution rate for a multi-component bubble. The dataset primarily summarizes the results of the first case, as the history effect turned out to be most significant in the first one.
