Effect of absorbate concentration level on dissolving translating bubble collapse governed by simultaneous heat and mass transfer

 We studied gas absorption from a rising spherical bubble when the concentration level of the absorbate in the absorbent is finite (finite dilution of absorbate approximation). It is showed that in the case of finite dilution the lateral convective term in the equation of mass transfer of the absorbate must be taken into account. It is found that the rate mass transfer and the rate of bubble collapse increases with the increase of the absorbate concentration level. Isothermal and nonisothermal absorptions are considered whereby the latter is described by coupled equations of mass and heat transfer. It is showed that the rate of mass transfer and the rate of bubble collapse decreases when the heat of absorption increases. Received on 28 May 1999
