management and physics of turbulent bubble suspensions in microgravity (BubSus)

abstract

1. Bubble management: To develop the capability to generate a virtually homogeneous monodisperse bubble suspension carried by a turbulent pipe flow where we control separately:
   • the bubble size;
   • the bubble mean separation; and
   • the Reynolds number of the carrying flow.
     
     

2. Physics of bubble turbulent flows: To have a first collection of data with the general aim to contribute to the understanding of bubble/turbulence interaction, long-time generation of large-scale structures in spatial bubble distribution and the statistics of bubble coalescence phenomena.
