Abstract |
The area of the contact surface of phases is one of the main hydrodynamic indicators
determining the separation and heat and mass transfer equipment calculations. Methods of evaluating
this indicator in the separation of multicomponent two-phase systems were considered. It was
established that the existing methods for determining the interfacial surface are empirical ones,
therefore limited in their applications. Consequently, the use of the corresponding approaches
is appropriate for certain technological equipment only. Due to the abovementioned reasons,
the universal analytical formula for determining the interfacial surface was developed. The approach
is based on both the deterministic and probabilistic mathematical models. The methodology was
approved on the example of separation of two-phase systems considering the different fractional
distribution of dispersed particles. It was proved that the area of the contact surface with an accuracy
to a dimensionless ratio depends on the volume concentration of the dispersed phase and the volume
of flow. The separate cases of evaluating the contact area ratio were considered for different laws of
the fractional distribution of dispersed particles. As a result, the dependence on the identification of
the abovementioned dimensionless ratio was proposed, as well as its limiting values were determined.
Finally, a need for the introduction of the correction factor was substantiated and practically proved
on the example of mass-transfer equipment. |
