Computational Simulations of Microbubbles

  • 374 Accesses

Abstract

Accurate tracking of microbubbles plays a significant role in many engineering processes. Computational methods, including the volume of fluid (VOF), and coupled level set and volume of fluid (CLSVOF) are validated against a comprehensive experimental dataset, including detailed information describing the interface deformation, and transient development of the stage by stage shape data. Using the fully developed shape and subsequent deformation of rising microbubbles that have been captured experimentally and analyzed in detail using image processing, the corresponding VOF and CLSVOF results are accurately assessed for the small-scale differences between these interface capturing methods. Computational prediction on the removal of microbubbles is also examined in a haemodialysis airtrap. Such a model can provide useful information about the effectiveness and performance of an airtrap which is a commonly device used in a clinical setting for kidney failure patients.
