Numerical Analysis of the Effects of Selected Geometrical Parameters and Fluid Properties on MHD Natural Convection Flow in an Inclined Elliptic Porous Enclosure with Localized Heating

Magnetohydrodynamic (MHD) natural convection flow and associated heat convection in an oriented elliptic enclosure has been investigated with numerical simulations. A magnetic field was applied to the cylindrical wall of the configuration, the top and bottom walls of the enclosure were circumferentially cooled and heated, respectively, while the extreme ends along the cross-section of the elliptic duct were considered adiabatic. The full governing equations in terms of continuity, momentum, and energy transport were transformed into nondimensional form and solved numerically using finite difference method adopting Gauss–Seidel iteration technique. The selected geometrical parameters and flow properties considered for the study were eccentricity (0, 0.2, 0.4, 0.6, and 0.8), angle of inclination (0°, 30°, 60°, and 90°), Hartmann number (0, 25, and 50), Grashof number (104, 105, and 106), and Darcy number (10−3, 10−4, and 10−5). The Prandtl number was held constant at 0.7. Numerical results were presented by velocity distributions as well as heat transfer characteristics in terms of local and average Nusselt numbers (i.e., rate of heat transfer). The optimum heat transfer rate was attained at e value of 0.8. Also, the heat transfer rate increased significantly between the angles of inclination 58° and 90°. In addition, Hartmann number increased with decreased heat transfer rate and flow circulation. A strong flow circulation (in terms of velocity distribution) was observed with increased Grashof and Darcy numbers. The combination of the geometric and fluid properties thereforHeat Trans Asian Res, 00(0): 1–33, 2016; Published online in Wiley Online Library (wileyonlinelibrary.com/journal/htj). DOI 10.1002/htj.21211e can be used to regulate the circulation and heat transfer characteristics of the flow in the enclosure. C⃝ 2016 Wiley Periodicals, Inc

COMPUTATION OF NATURAL CONVECTION IN A POROUS PARALLELOGRAMMIC ENCLOSURE WITH A MAGNETIC FIELD

Detailed numerical calculations are presented in this paper for natural convection in a porous parallelogrammic enclosure with a magnetic field. The inclined walls are maintained isothermally at different temperatures. The top and bottom horizontal straight walls are kept adiabatic. To simplify the effort in matching the grid mesh with the inclined walls of the parallelogrammic region/geometry, the computational domain is mapped onto a rectangular shape using a non-linear axis transformation. Transport equations are modeled by a stream-vorticity formulation then expressed in the new coordinate system and solved numerically by a finite difference method. Based upon the numerical predictions, we found the convection modes within the enclosure depended upon the Rayleigh number and the inclination angle. As the value of magnetic field is made larger, the strength of the heat transfer is progressively suppressed. Tuning the inclination angle decreases the heat transfer performance

Theorising Indigenous Sociology: Australian perspectives

Indigenous social issues are a topic of regular media interest, but there is scope for much work to be done by Australian sociologists to provide new ways of understanding these issues. The contested terrain of the field, the need for new concepts and frameworks, debates about the possibilities for an Indigenous sociology, and the call for a specifically Australian approach, are some of the challenges and dilemmas for the field. A growing, but small group of Australian sociologist are responding to these dilemmas through a range of interesting and innovative theoretical approaches. To provide an opportunity to explore these developments and to encourage greater collaboration with other researchers in the field a two-day workshop was co-hosted by the Australian Sociological Association (TASA) Sociology of Indigenous Issues Thematic Group and the Department of Sociology and Social Policy at the University of Sydney. The workshop organisers were Dr Deirdre Howard-Wagner (University of Sydney), Dr Daphne Habibis (University of Tasmania) and Dr Theresa Petray (James Cook University). This double blind refereed edited workshop collection consists of six 3000 word full papers from the 18 papers presented at a two-day workshop held at the University of Sydney on Thursday 19 July and Friday 20 July 2012

Conditionality, Recognition and Indigenous Housing Policy in Australia

This paper draws on ideas of recognition and the intercultural as a way of examining the impact of welfare conditionality on Indigenous housing policy in Australia. The increased application of welfare conditionality has occurred in tandem with „mainstreaming‟ of housing management and provision, and regulation of Indigenous Community Organisations. (ICOs). These developments raise policy and practice questions about the effectiveness of such approaches in achieving desired housing outcomes because of questions about their alignment with Indigenous norms and values. The paper argues that the embedded nature of individuals in their social and cultural locations requires the development of policy paradigms that are adapted to these realities. The idea of a recognition space extends the idea of conditionality to one involving moral relationships of duty and care between the individual, Indigenous formal and informal governance structures and the state and its agents. This can be used to build a framework for the development of flexible and adaptive housing policies that are culturally respectful and address the differences in housing values between tenants and housing agencies

Improving housing and service responses to domestic and family violence for Indigenous individuals and families

Domestic and family violence is the largest driver of homelessness for women and children in Australia. Over the past decade Australian governments have invested in significant legislative, policy and service reforms to mitigate the impact of domestic and family violence for women and children. Little, however, is known as to the impact of these reforms on Aboriginal individuals and their families and their relationship to housing. This research therefore examines how housing and other service responses need to be improved to meet the needs of Aboriginal individuals and families in the aftermath of domestic and family violence. It draws on data from a rapid evidence and policy review; as well as qualitative interviews with nine Indigenous women service-users and 30 stakeholders including policy makers and service providers, in two regional cities in New South Wales and the Northern Territory
