TACKLING COMPLEX TURBULENT SURFACE PHENOMENA BY ANALYTICAL SURFACE-FUNCTIONS

Analytical surface-function (ASF) methods for surface boundary conditions of turbulent flows are reviewed.

Nonlinearity in the study of vortex-induced vibration

Abstract: The presentation will focus mainly on the problem of vortex-induced vibration experienced by risers used by the oil & gas companies in their off-shore installations.

Next Generation Networks Systems (Engineering & Computer Science Seminar)

Professor Gerard Parr is the UK lead of the India-UK Advanced Technology Centre of Excellence in Next Generation Networks Systems and Services.

On catastrophic sliding bifurcations, and hunting ducks in nonsmooth flows

Abstract: The theory of nonsmooth dynamical systems is still young, but fruitful. We will present some recent theoretical advances, with application to experimental results from a superconducting sensor, and open problems of relevance to mechanical systems with friction or impact, such as the occurrence of nondeterministic chaos.

Particle dynamics simulation of rock fracture

Modelling the fracture of brittle materials can be difficult because it involves the fast propagation of cracks.

Chaos control methods applied to avoid bifurcations

Chaos may be exploited in order to design dynamical systems that may quickly react to some new situation, changing conditions and their response.

CADR Seminars (Two Presentations)

Computational Investigation of Turbidity Currents and River Outflows

We will present an overview of high-resolution, Navier-Stokes based simulations of gravity/turbidity currents and river outflows.

Cavity dynamics of water entry for spheres and ballistic projectiles

The hydrodynamics of water entry are investigated experimentally for low Froude numbers for spheres and ballistic projectiles.

Regenerative Chatter in Turning

In this talk, I will focus on some simple models for regenerative chatter.
