Investigation of a drag reduction on a circular cylinder in rotary oscillation [PDF]
, 2001 Drag reduction in two-dimensional flow over a circular cylinder, achieved using rotary oscillation, was investigated with computational simulations. In the experiments of Tokumaru & Dimotakis (1991), this mechanism was observed to yield up to 80% drag ...

Effect of Pressure on the Superconducting Properties of Tl2Ba2Ca2Cu3O9-δ
Crystals, 2018 This study investigated the application of pressure on the superconducting properties of a thallium-based cuprate, namely Tl2Ba2Ca2Cu3O9-δ (Tl-2223). The superconducting transition temperature (Tc) and the critical current density (Jc) were studied

High pressure study of BaFe2As2 - role of hydrostaticity and uniaxial stress
, 2009 We investigate the evolution of the electrical resistivity of BaFe2As2 single crystals with pressure. The samples used were from the same batch grown from self flux and showed properties that were highly reproducible. Samples were pressurised using three

Drag and lift forces when moving in a cohesive granular medium [PDF]
EPJ Web of ConferencesWhen a cylinder moves horizontally in a dry granular medium, it experiences both a drag force and a significant lift force, despite the symmetry of the geometry. The lift force arises due to the unique frictional nature of granular material rheology. The
