Effects of axisymmetric strain on a passive scalar field: modelling and experiment

Homogeneous, approximately isotropic turbulence at two Taylor-scale Reynolds numbers, Rλ=50, 190, with a mean transverse temperature gradient is passed through an axisymmetric contraction. The effects of the straining on the velocity field, and on the passive scalar field, are investigated within th...
