Fluid Dynamics Laboratory
The ICTP Fluid Dynamics Laboratory is a world‐class research
facility whose activities range from quantum to classical fluid
flows and whose centrepiece is an apparatus capable of producing
the highest levels of controlled buoyancy‐driven turbulence in the
world. It operates at a temperature of near‐absolute zero and
provides high‐resolution data at the far frontier of fluid
From its position atop a rotating platform, ICTP's turbulent convection experiment provides data applicable to large‐scale natural phenomena like atmospheric and solar convection in a range of control parameters not possible elsewhere.
Recent experiments have taken particular advantage of the possibility to apply more realistic boundary conditions, particularly the more two‐dimensional aspect ratios characteristic of natural extended systems. Novel techniques involving the propagation of high frequency thermal waves have made it possible to provide the first direct mapping of a thermally "superconducting" core at high turbulent intensities, which has been one of the key assumptions in phenomenological theories of turbulent convection.
