Dye visualisation techniques and CFD are used to characterise the flow of viscoplastic CarbopolTM solutions in stirred vessel systems over multiple scales. Centrally-mounted, geometrically-similar Rushton turbine (RT) impellers are used to agitate various Carbopol 980 (C980) fluids. The dimensionless cavern diameters, Dc/D, are scaled against a com...
This paper describes an application of 3D density reconstruction from a limited number of Background Oriented Schlieren (BOS) images in a large high speed wind tunnel. The tested flow is a counter-flowing hot jet facing the transonic main flow. Ray deviation maps captured by 12 synchronized cameras are combined to reconstruct the three dimensional ...

In the development of a ventricular assist device, computational fluid dynamics (CFD) analysis is an efficient tool to obtain the best design before making the final prototype. In this study, different designs of a centrifugal blood pump were developed to investigate flow characteristics and performance. This study assumed the blood flow as being a...

The variations of flow structure and heat transfer characteristics of impinging air jets with respect to mesh solidity are compared for two mesh screen locations at small nozzle-to-plate spacings. Results show that the uniform incoming flow structure produces higher heat transfer rates in the impingement region. The heat transfer enhancement largel...
Modelling of steady-state magneto-convective flows has been performed for typical geometries of currently investigated Helium-Cooled Lithium Lead (HCLL) blankets. For fusion relevant magnetic fields the flow has been studied for a purely diffusive heat transfer regime and for a convective regime with finite Peclet number. The effect of the directio...
