tvåfasflerfasflöde
tvåfasflerfasflöde is a term used in fluid mechanics to describe a flow regime that contains both two‑phase and multiphase characteristics. The name is derived from Swedish where “tvåfas” means two‑phase, “flerfas” means multiphase, and “flöde” means flow. In practice the concept applies to systems in which two distinct phases (for example liquid and gas) coexist alongside additional immiscible phases such as a solid particulate or a third fluid. This hybrid flow situation can occur in natural settings, like sediment‑laden rivers carrying gas bubbles, as well as in industrial processes such as oil and gas pipelines, chemical reactors, and thermal power plant condensers.
Understanding tvåfasflerfasflöde is important because each phase interacts with the others, influencing pressure drop, heat transfer,
The practical implications of accurately characterizing tvåfasflerfasflöde include improved design of pipeline transport systems, more efficient
