Verhalten gedehnter Flüssigkeitsfäden in viskosen Flüssig/Flüssig‐ Systemen

The stability of jets in elongational flow is exploited to receive thin threads before break up. Fine drops can be generated in suitable geometries with comparable large cross flow areas. The examination deals with the stability of liquid threads simultaneously extended with the continuous phase in convergent flow. Break up limits and regimes are discussed.     

Membrangestützte Flüssig/Flüssig‐Extraktion – Wo stehen wir heute?

Thanks to advancements in materials science and manufacturing technology, membranes are now available for stable liquid‐liquid extraction processes. Rigorous calculation models can be used to calculate the membrane areas required for a given separation task as well as to optimize the module design. In rapid tests, the basic suitability and kinetic parameters can be determined. Thus, the general requirements are for utilizing the specific advantages of this separation technology in technical applications are fullfilled.
