Particle impaction on a cylinder in a cross flow is investigated with the use of Direct Numerical Simulations (DNS), with a focus on the effect of turbulence on the impaction efficiency. It is found that for particles with Stokes numbers in the boundary stopping mode there is up to ten times more front side impaction for turbulence with a large...

We investigated the rotation of non-spherical particles (rod-like and disk-like) in turbulent channel flow with focus on inertial effects. A direct numerical simulation (DNS) with an Eulerian-Lagrangian approach was performed. A wide range of particle aspect ratios, λ, ranging from 0.01 to 50 were considered for Stokes numbers St equal to 1 and...

A suspension of oblate spheroidal (disk-like) particles in turbulent channel flow has been investigated with focus on the translational and rotational particle statistics. The effects of particle aspect ratio and inertia have been explored. The disk-like particles exhibited a significant preferential orientation in the plane of the mean shear....

The incompressible flow past a 6:1 prolate spheroid with an inclination angle of 45o at Re = 3,000 has been studied by means of direct numerical simulations (DNS). The Reynolds number is based on the inflow velocity and minor-axis length. The preliminary results presented here are focused mainly on vortex dynamics and vortical structures in the...

Sweden is entering the ageing society. On a national level, and in a cyclic process with a time lap of 30 to 40 years, three architecture competitions have been realized during the 20th century in order to renew spatial thinking concerning housing for dependent and frail persons in need of daily care and caring, in the following termed...

Shortly before the EU summit in Gothenburg in 2001, the University of Gothenburg and Chalmers University of Technology arranged their first international conference in learning for sustainable development, entitled „Knowledge and Learning for a Sustainable Society?. At the UN World Summit on Sustainable Development in Johannesburg 2002, Sweden...

The work to incorporate sustainable development into courses at university level is a complex task. It is therefore a challenge for everyone involved in the teacher training program at any university. At the University of Gothenburg, Gothenburg, Sweden, the main compulsory course involving sustainable development is given during the first...

Three-dimensional numerical calculations of laminar vortex shedding behind a linearly tapered circular cylinder with taper ratio 75:1 have been carried out at a Reynolds number 131 (based on the large diameter and the uniform inflow velocity) using a Finite Volume code. Computations were performed on a staggered-Cartesian grid and a direct...
