Ambesi, D. (author), Kleijn, C.R. (author), Den Hartog, E.A. (author), Bouma, R.H.B. (author), Brasser, P. (author)In chemical, biological, radiological, and nuclear protective clothing, a layer of activated carbon material in between two textile layers provides protection against hazardous gases. A cylinder in cross flow, sheathed by such material, is generally used to experimentally test the garment properties. This is, however, complicated and predictive...journal article 2013

Hoang, D.A. (author), Portela, L.M. (author), Kleijn, C.R. (author), Kreutzer, M.T. (author), Van Steijn, V. (author)The breakup of droplets due to creeping motion in a confined microchannel geometry is studied using three-dimensional numerical simulations. Analogously to unconfined droplets, there exist two distinct breakup phases: (i) a quasi-steady droplet deformation driven by the externally applied flow; and (ii) a surface-tension-driven three-dimensional...journal article 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

Abbate, G. (author), Kleijn, C.R. (author), Thijsse, B.J. (author), Engeln, R. (author), Van de Sanden, M.C.M. (author), Schram, D.C. (author)The gas dynamics of a stationary hot-gas jet supersonically expanding into a low pressure environment is studied through numerical simulations. A hybrid coupled continuum-molecular approach is used to model the flow field. Due to the low pressure and high thermodynamic gradients, continuum mechanics results are doubtful, while, because of its...journal article 2008
