| Effect of Bulk and Interfacial Rheological Properties on Bubble Dissolution (2001) | |||||||||||
Abstract | |||||||||||
| This paper describes theoretical calculations of the combined effect of bulk and interracial rheological properties on dissolution behavior of a bubble in an infinite medium at saturated conditions. Either bulk or interracial elasticity can stop the bubble dissolution process, and stability criteria are defined for the elastic cases. In the case of an elastic interface with dilation modulus Ed and a bubble with an initial radius R0 and initial interracial tension σ0, the bubble is stabilized as it has shrunk to a relative radius of ε = R/R0 = exp(-σ0/(2Ed)). In case of an elastic bulk with modulus G a bubble will shrink until GR0 = 4σ0ε3/(1 - 5ε4 4ε3) is fulfilled. Bulk and interracial viscosity can retard the dissolution process if their magnitude exceeds a certain critical value but will never completely stop bubble dissolution | |||||||||||
