Magnetorheo]ogical (MR) fluids are colloidal suspensions of pammagnetic particles in a non-magnetic fluid. These fluids, along with their electrical analogues, electrorheologica] (ER) fluids, have been proposed as controllable fluids, for use in electromechanical devices such as dampers, clutches and brakes. [1] When exposed to an external magnetic field, the particles acquire dipole moments ag...

Over the past decade, some groups have reported that nanofluids, which are liquids containing suspensions of nanoparticles, have substantially higher thermal conductivity than that of the base fluids. However, the reported high thermal conductivity sometimes cannot be reproduced. Theoretically, potential mechanisms leading to this enhancement are still under scrutiny. In this thesis, we present...

Optical manipulation of particulate-loaded, highly scattering (opaque) suspensions is considered impossible. Here we demonstrate theoretically and experimentally optical manipulation of the local properties of such opaque suspensions. We show that the optical forces exerted by multiply-scattered light give rise to dense shock fronts of particle concentration, propagating deep inside the opaque ...

Flow properties of complex fluids such as colloidal suspensions, polymer solutions, fiber suspensions and blood have a vital function in many technological applications and biological systems. Yet, the basic knowledge on their properties is inadequate for many practical purposes. One important reason for this has been the lack of effective experimental methods that would allow detailed study of...

First of all, I will introduce the basics of Newtonian fluids, followed by differences in comparison to non-Newtonian fluids. Following that, I will consider suspensions and focus on the shear thickening phenomena. Different theories behind that lead us to an order-disorder system and a hydro-clusters formulation. Finally, I will present its applications and prospects for the future.
