The transport properties of an AB random copolymer melt near the order-disorder phase transition are examined by using a mode coupling approach. The key parameters of the model are the volume fraction of type A monomers, f, the Flory χ parameter, and a parametert λ that characterizes the...

The velocity distribution for a homogeneous shear flow of smooth nearly elastic disks is determined using a perturbation solution of the linearised Boltzmann equation. An expansion in the parameter εI=(1−e)1/2 is used, where e is the coefficient of restitution. In the leading order...

The growth rates of the hydrodynamic modes in the homogeneous sheared state of a granular material are determined by solving the Boltzmann equation. The steady velocity distribution is considered to be the product of the Maxwell–Boltzmann distribution and a Hermite polynomial expansion in the...
