Haffner, M.E.A. (author), Elsinga, M.G. (author)While Dutch housing policy has been moving towards ‘more market’ influences in this century, in response to the triple recession that the Netherlands underwent in the period 2009-2013, government started promoting a participation society. In order to analyse the impact in practice of these developments on vulnerabilities of households, a Dutch...conference paper 2018

Goudar Vishwanathappa, M. (author), Breugem, W.P. (author), Jodai, Y. (author), Elsinga, G.E. (author)For channel flow, we explore how the interaction of weak eddies produces additional eddies by means of auto-generation. This is done by DNS of two eddies with different initial strengths, initial sizes and initial stream-wise spacing between them. The numerical procedure followed is similar to Zhou et al[1]. The two eddies merge into a single...conference paper 2016

Zhuang, T. (author), Qian, QK (author), Visscher, H.J. (author), Elsinga, M.G. (author)China’s fast growth of economy and urbanization has created a world record on its own since its reform and opening-up policy in late 1970s. This drives mass demolition and reconstruction and leaves a short lifespan of existing buildings through unsustainable urban renewal. Many developed countries/regions, such as the UK and Hong Kong, have long...conference paper 2016

Highly porous materials are found in various industrial applications and environmental flows. In previous studies it was found that a turbulent flow along a highly porous wall experiences a higher skin friction as compared to a solid wall with similar surface roughness when the so-called permeability Reynolds number (Re_K) is larger than O(1)....conference paper 2015

Eisma, J. (author), Westerweel, J. (author), Elsinga, G.E. (author)Experimental research is presented on the characteristics of interfaces and internal layers that are present in a turbulent boundary layer (TBL). Both the turbulent non-turbulent interface (T/NT) and internal shear layers are detected in snapshots of the stereo-PIV data. It turns out that the internal layers exhibit similar characteristics...conference paper 2015

Goudar, M.V. (author), Elsinga, G.E. (author)Pair dispersion is studied to model scalar transport in many natural and industrial applications. The link between the particle pair dispersion and coherent flow structures is explored in this work. This was done by kinematically simulating tracer particles in an ideal flow structure [Elsinga and Marusic (2010)] extracted from an isotropic...conference paper 2015

Fiscaletti, D. (author), Attili, A. (author), Bisetti, F. (author), Elsinga, G.E. (author)The interaction between scales is investigated in a turbulent mixing layer. The large-scale amplitude modulation of the small scales already observed in other works depends on the crosswise location. Large-scale positive fluctuations correlate with a stronger activity of the small scales on the low speed-side of the mixing layer, and a reduced...conference paper 2015

Gul, M. (author), Elsinga, G.E. (author), Westerweel, J. (author)This study investigates the effect of the Taylor-Couette geometry, namely the aspect ratio, Γ, and the gap width ratio, ƞ, on the torque hysteresis reported by [1]. Measurements were taken at two shear Reynolds numbers, Re s, of 5.5x10⁴ and 9x10⁴.The torque was recorded while decreasing or increasing the rotation frequency ratio a=-fo/fi,...conference paper 2015

Teye, A.L. (author), De Haan, J. (author), Elsinga, M. (author)As in many countries, the Dutch housing market was severely hit by the recent financial crisis. Following the recession, the average house price in the Netherlands fell by almost 25% and the proportion of homeowners with mortgage payment arrears nearly doubled. In this paper, we study mortgage payment arrears in the Netherlands and investigate...conference paper 2015

In lieu of this, the two main institutions through which government provided and managed public housing – the TDC and SHC sold off most of their dwellings. The few remaining dwellings were transferred to local authorities to own and manage. There have been...conference paper 2015

It examines the housing tenure change, policy instruments, and impacts social structures in different time periods. After the welfare period of 1949-77, the dual provision period of 1978-1998, and the market dominant period of 1999-2011, China’s housing policy was again reformed...conference paper 2014
