How is flying possible in a superfluid? Probing lift generation in liquid helium-4 to identify its Newtonian features

Project goals

Superfluid helium-4 is a unique cryogenic liquid and its similarities with classical Newtonian fluids have yet to be neatly identified. In view of addressing this open question, we will investigate in unprecedented detail a canonical problem, lift generation, i.e. flying. This will also indicate conditions in which a superfluid wind tunnel may become a viable option to study classical turbulent flows.

    Jak je možné létání v supratekutině? Zkoumání generování vztlaku v kapalném heliu-4 za účelem identifikace jeho newtonských rysů

  • Annotation in Czech

    Supratekuté helium-4 je jedinečná kryogenní kapalina a její podobnosti s klasickými newtonskými tekutinami musí být ještě přesně identifikovány. Se zřetelem na řešení této otevřené otázky prozkoumáme v nebývalém detailu kanonický problém, generování vztlaku, tj. létání. To také naznačí podmínky, ve kterých se supratekutý aerodynamický tunel může stát funkční možností pro studium klasických turbulentních proudění.
