... and pressure gradient are the two main parameters for comparison. IFE's CO 2 flow loop, with an inner diameter (ID) of 44 mm, operates for two-phase flows over a large range of pressures and temperatures to cover the equilibrium line. A set of experiments was run to simulate similar conditions, according...

... in this study for two different ranges of liquid viscosity. The first proposed model modifies Brodkey (1967) critical bubble agglomeration diameter by including liquid viscosity, which is applicable for liquid viscosity up to 100 mPa.s. The second model, which is applicable for liquid viscosities above 100...

... volumes. The results show that OLGA is unable to accurately predict both the total liquid and aqueous phase volumes when the actual sphere diameter is used, but this is improved when the sphere is modelled as larger than reality. Adjusting the leakage factor ‘through’ the sphere does not affect...

Because of the importance of this topic, many investigators have developed models for predicting critical deposition velocities. For example, Figure 1 shows a prediction of particle transport velocity using...
