Droplet nuclei caustic formations in exhaled vortex rings
Papoutsakis, Andreas; Danaila , Ionut; Luddens , Francky; Gavaises , Manolis (2022-03-10)Vortex ring (VR) structures occur in light or hoarse cough configurations. These instances consist of short impulses of exhaled air resulting to a self-contained structure that can travel large distances. The present study ... -
Numerical investigation of shock-induced bubble collapse dynamics and fluid–solid interactions during shock-wave lithotripsy
Papoutsakis, Andreas; Koukas, Evangelos; Gavaises, Manolis (2023-05-31)In this paper we investigate the bubble collapse dynamics under shock-induced loading near soft and rigid bio-materials, during shock wave lithotripsy. A novel numerical framework was developed, that employs a Diffuse ... -
Numerical study of real gas effects during bubble collapse using a disequilibrium multiphase model
Papoutsakis, Andreas; Bidi, Saeed; Koukouvinis , Phoevos Koukouvinis; Shams , Armand; Gavaises, Manolis (2022-11-30)An explicit density-based solver of the Euler equations for inviscid and immiscible gas–liquid flow media is coupled with real-fluid thermodynamic equations of state supporting mild dissociation and calibrated with shock ...
