“…Most studies reported in literature have focused on the impact of variable viscosity on the large scales. Chhabra et al (2005) and Talbot et al (2013) studied turbulent jet flows, where the viscosity between jet fluid and host fluid differs. They observed, compared to a flow with uniform viscosity, that the relationship between production and dissipation of turbulent energy is altered and that the entrainment and the spreading rates of the jet flow are changed.…”

“…Such situations occur in turbulent jets, and the concentration-dependent viscosity may modify the entrainment mechanism during the transition to turbulence. 8 A strong gradient of viscosity may also relaminarize mixing zones at late stage in magma fountains. 9 Still, the precise role of variable viscosity is not completely understood as it is entangled with the complex features of inhomogeneous and anisotropic turbulent flows.…”

“…gas. Talbot, Danaila & Renou (2013) experimentally studied mixing in the near field of a round jet with (viscosity ratio of the outer and inner flows) and found that VVM evolves to a self-similar solution faster compared with CVM. In the same premise, for , Voivenel et al.…”

“…gas. Talbot, Danaila & Renou (2013) experimentally studied mixing in the near field of a round jet with m = 5.5 (viscosity ratio of the outer and inner flows) and found that VVM evolves to a self-similar solution faster compared with CVM. In the same premise, for m = 3.5, Voivenel et al (2016) observed self-similar profiles of velocity starting from x/d ≥ 4.5 while the Taylor microscale Reynolds number was not self-similar.…”
