The present study in spin stabilised disc aerodynamics builds on previous experimental wind tunnel work to broaden the knowledge base through CFD simulation without the necessity for high facility or time cost. The current experimental database from previous studies is extensive enough for sufficient validation to be conducted on known geometries. From there, the limitations of CFD studies for ...

Continuous flow spinning disc processing (SDP), which has extremely rapid mixing under plug flow conditions, effective heat and mass transfer, allowing high throughput with low wastage solvent efficiency, is effective in gaining access to superparamagnetic Fe3O4 nanoparticles at room temperature. These are formed by passing ammonia gas over a thin aqueous film of Fe which is introduced through ...

We present a systematic study of GX 339-4 in both its very high and low hard states from simultaneous observations made with XMM-Newton and RXTE in 2004 and 2006. The X-ray spectra of both these extreme states exhibit strong reflection signatures, with a broad, skewed Fe-Kα line clearly visible above the continuum. Using a newly developed, self-consistent reflection model which implicitly inclu...

In this paper, we present a fully integrated and automated lab-on-a-disc for the rapid determination of the total phenolic content (TPC) and antioxidant activity (AA) of beverage samples. The simultaneous determinations of TPC and AA on a spinning disc were achieved by integrating three independent analytical techniques: the Folin-Ciocalteu method that is used to measure TPC, the 2,2-diphenyl-1...

In this paper we analyse the propagation of warps in protostellar circumbinary discs. We use these systems as a test environment in which to study warp propagation in the bendingwave regime, with the addition of an external torque due to the binary gravitational potential. In particular, we want to test the linear regime, for which an analytic theory has been developed. In order to do so, we fi...

This paper investigates the effects of disc deformation on tilting-induced vibration a splined spinning with axial-fixed boundaries.The purpose is to provide an intuitive interpretation variance wet clutch system different deformed discs. First, tilting models flat and discs are derived by introducing distinctive shape functions. Additionally, inner spline interface chosen as friction boundary....

Luminous active galactic nuclei (AGN) and X-Ray binaries (XRBs) often contain geometrically thin, radiatively cooled accretion discs. According to theory, these are -- in many cases initially highly misaligned with the black hole equator. In this work, we present first general relativistic magnetohydrodynamic simulations of very thin (h/r~0.015-0.05) discs around rapidly spinning (a~0.9) holes ...
