Pharmacovigilance is, in essence, the process of monitoring the everyday use of medicines
to identify previously unrecognized adverse drug reactions thereby assessing their …

Drag reduction due to dilute addition of high polymers has been known for about fifty years.
In spite of this long history, many aspects of the problem remain poorly understood. Two of …

We present an overview of the statistical properties of turbulence in two-dimensional (2D)
fluids. After a brief recapitulation of well-known results for statistically homogeneous and …

Particle image velocimetry (PIV) measurement technique provides an excellent opportunity
for investigating instantaneous spatial structures which are not always possible with point …

In this paper, we present two new numerical algorithms for updating the equations of motion
for a viscoelastic fluid that can be described by the finite extensible nonlinear elastic polymer …

Decaying homogeneous, isotropic turbulence is investigated using a phenomenological
model based on the three-dimensional turbulent energy spectra. We generalize the …

Turbulent motions in a fluid decay at a certain rate once stirring has stopped. The role of the
most basic parameter in fluid mechanics, the Reynolds number, in setting the decay rate is …

Progress in understanding turbulent drag reduction by polymer additives has recently been
made on several fronts. The near-wall dynamics of Newtonian turbulence is becoming better …

We present a new finite-difference formulation to update the conformation tensor in
dumbbell models (eg, Oldroyd-B, FENE-P, Giesekus) that guarantees positive eigenvalues …
