Interplay of convective heat transfer and turbulent flows with rotation in classical and quantum phases of cryogenic helium

Experimental studies of of complementary classical and quantum convective heat flows and turbulence are proposed with the emphasis of their interplay with rotation. Two rotating platforms will be designed and built, one of them to allow experimental investigation of highly turbulent Rayleigh-Benard convection under rotation, with the emhasis to determine the influence of non-Oberbeck-Boussinesq effects. Based on theoretical/numerical prediction of flow phase diagram of spherical thermal counterflow, experimental realization of spherical and cylindrical thermal counterflow will be investigated experimentally at rest and under influence of rotation provided by the second platform. Results of complementary classical and quantum flows will be analyzed with the aim of deeper undestanding of complementary classical and quantum turbulent flows.
