Moya, R. (author), Salim, F. (author), Williams, M. (author), Sharaidin, K. (author)The aims of the Flexing Wind project, investigated in an intensive cross-disciplinary course, were twofold. First was to learn about aerodynamic phenomena around buildings. Second was to explore ways to observe, measure, and control the negative effects of wind around specific pedestrian areas, tram stops, and public sites in Melbourne City....conference paper 2013

Pereira, S.P. (author), Vuik, K. (author), Pinho, F.T. (author), Nobrega, J.M. (author)The present work explores the massively parallel capabilities of the most advanced architecture of graphics processing units (GPUs) code named “Fermi”, on a two-dimensional unstructured cell-centred finite volume code. We use the SIMPLE algorithm to solve the continuity and momentum equations that was fully ported to the GPU. The benefits of...conference paper 2013

Derakhshani, S.M. (author), Schott, D.L. (author), Lodewijks, G. (author)Dust emissions can have significant effects on the human health, environment and industry equipment. Understanding the dust generation process helps to select a suitable dust preventing approach and also is useful to evaluate the environmental impact of dust emission. To describe these processes, numerical methods such as Computational Fluid...conference paper 2013

Hoang, D.A. (author), Van Steijn, V. (author), Portela, L.M. (author), Kreutzer, M.T. (author), Kleijn, C.R. (author)Modeling of low-Capillary number segmented flows in microchannels is important for the design of microfluidic devices. We present numerical validations of microfluidic flow simulations using the volume-of-fluid (VOF) method as implemented in OpenFOAM. Two benchmark cases were investigated to ensure the reliability of OpenFOAM in modeling complex...conference paper 2012

Van Zuijlen, A.H. (author), Bijl, H. (author)Computational fluid-structure interaction is most commonly performed using a partitioned approach. For strongly coupled problems sub-iterations are required, increasing computational time as flow and structure have to be resolved multiple times every time step. Many sub-iteration techniques exist that improve robustness and convergence, although...conference paper 2009

Duda, P. (author), Cebula, A. (author), Dwornicka, R. (author)High thermal stresses are created during the operation of power block devices such as boiler drums, outlet headers, steam valves, turbines and heat exchangers. Due to a cyclic character of such stresses, a phenomenon of low-cyclic fatigue occurs, which may lead to the formation of fractures. Manufacturers of power block devices frequently advice...conference paper 2006

Tabor, G. (author), Tame, D. (author), Pierron, F. (author), Young, P.G. (author), Watkinson, A. (author), Thompson, J. (author)Biomedical flow problems tend to involve domains which are geometrically complex over a range of scales. Much effort has gone into developing tools for generating computational meshes automatically from medical scan data (MRI, CT), allowing the easy creation of patient-specific models of the flow domain, and hence the investigation of flow under...conference paper 2006

Verstraete, T. (author), Alsalihi, Z. (author), Van den Braembussche, R.A. (author)A Conjugate Heat Transfer (CHT) analysis allows the calculation of the heat transfer and temperature of a body placed in a fluid. The CHT analysis takes into account both the conduction in the solid and the convection in the fluid. Present paper describes a CHT method that uses two separate solvers: one CFD solver dedicated to the flow...conference paper 2006

Regnström, B. (author)The Theodorsen-Garrick conformal mapping is used to make a grid around a wing section and to compute the potential flow around it. The potential flow is a solution to the incompressible Euler equations and can be used to verify the inviscid part of RANS codes.conference paper 2006

Aglave, R.H. (author), Warnatz, J. (author)Detailed mechanisms describing ignition, flame propagation and pollutant formation typically involve several hundred species and elementary reactions, prohibiting their use in practical three-dimensional engine simulations. Conventionally reduced mechanisms often fail to predict minor radicals and pollutant precursors. The ILDM-method is an...conference paper 2006

Diarra, D. (author), Velaga, D. (author), Lucka, K. (author), Köhne, H. (author)In this paper the fluid dynamics of three cool flame vaporizers are investigated numerically, using a commercial CFD-code. The paper focuses on analyzing local and global residence time distributions (RTD). Two approaches have been used to model the RTD: a transient step tracer model (which serves as a reference) and a dispersed phase tracer model.conference paper 2006

Yao, J. (author), Patel, M.K. (author), Yao, Y. (author), Mason, P.J. (author)Numerical simulation has been conducted for the investigation of heat transfer in a rectangular, highaspect ratio microchannel with heat sinks, similar to an experimental study. Water at ambient temperature is used as working fluid and the heating power of 180 W is introduced via electronic cartridges in the solids. Three channel heights of 0.3...conference paper 2006

Alauzet, F. (author)This paper presents an accurate approach to simulate the sonic boom of a supersonic aircraft. The near field flow is modeled by the conservative Euler equations and is solved using a finite volume approach on adapted unstructured tetrahedral meshes. Then, from the CFD solution, the pressure distribution under the aircraft is extracted and used...conference paper 2006

Christakis, N. (author), Chapelle, P. (author), Patel, M.K. (author), Cross, M. (author)Many industrial processes involve particulates with materials ranging from pharmaceuticals, ceramics, cosmetics and foods. Common to all these particulate processes is the discharge of granular material from bins/hoppers in either mass flow mode (i.e. all material regions in the domain are in motion) or core flow mode (i.e. there is a flowing...conference paper 2006
