Superfluids might share attribute with frequent fluids

Each fluid — from Earth’s ambiance to blood pumping via the human physique — has viscosity, a quantifiable attribute describing how the fluid will deform when it encounters another matter. If the viscosity is greater, the fluid flows calmly, a state often called laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent circulation. The diploma of laminar or turbulent circulation is known as the Reynolds quantity, which is inversely proportional to the viscosity. Nonetheless, this Reynolds similitude doesn’t apply to quantum superfluids. A researcher has theorized a solution to study the Reynolds similitude in superfluids, which might display the existence of quantum viscosity in superfluids.
