Sparse random graphs: Eigenvalues and Eigenvectors
We elucidate the universal properties of homogeneous, isotropic SBF turbulence, in the absence of any macroscopic (mean) concentration gradient, by measuring the scaling exponents of the equal-time structure functions of the velocity field u, the concentration field ψ and the concentration gradient field b = ∇ψ .

We also propose a new shell model for the gradient of the concentration field and numerically solve it as well as the shell model for scalar concentration field.
Universality of scaling and multiscaling in turbulent symmetric binary fluids
The results from both our DNS of the SBF equations and shellmodel studies are complementary to and agree well with each other and bring out the multiscaling of the velocity and concentration gradient fields and simple scaling of the concentration field.
