Comprehensive Modeling of Precipitation and Fouling in Turbulent Pipe Flow

摘要: Supersaturation with respect to an active compound triggers several precipitation-related processes that may proceed (essentially concurrently) along the flow path. The interaction between fluid dynamics and physicochemical (i.e., nucleation, particle growth, coagulation) leads axial variation of bulk properties (species concentration size distribution) ionic particulate deposition rates at pipe wall. To simulate this complicated system, very simple hydrodynamics (plug flow) is combined rather comprehensive modeling phenomena. Considerable effort devoted optimization computational requirements, thus developing a numerical algorithm efficient flexible enough cope even more demanding future tasks such as inclusion mixing. performance model examined using, test case, precipitation sparingly soluble salt under conditions typical for geothermal installations. An extensive study effects initial saturation ratio tendency coagulation on rate distribution carried out.
