Analysis of scalar dissipation in terms of vorticity geometry in isotropic turbulence

This numerical study, which may model any Lagrangian evolution of orientation, shows that the scalar gradient does not align with the equilibrium direction if nonstationary ef-

The stable fixed point of the orientation equation of a scalar gradient – referred to as the equilibrium direction – is in general different from the compressional direction and is

In fact in this case, the metric is induced by the inertia operator Λ := HD (with respect to the L 2 inner product on the tangent bundle).. Moreover, we present a thorough study of

Phenomenological scalings for the inertial ranges in both the IC and the forward enstrophy cascade will be proposed for the scalar flux spectrum F s k d and the scalar variance

Phenomenological scalings for the inertial ranges in both the inverse cascade and the forward enstrophy cascade will be proposed for the scalar flux spectrum F (k) and the

We think of scalar curvature as a Riemannin incarnation of mean cur- vature (1) and we search for constraints on global geometric invariants of n-spaces X with Sc(X) > 0 that

since hearers inferred a similar probability of two and three letters having checks. If the speaker saw two out of three letters and said ‘one of the letters has a check inside’,
