Storage Bins

The flow of bulk solids such as ore, coal, sugar and salt from storage bins depends on the pressures exerted by the bin walls on the solids. In the past the flow properties of bins have been determined on the basis of steady flow pressures. Recent experimental and theoretical work has shown that much larger pressures may be exerted on the solids during the initial filling of the bin. In this paper the effect of these initial pressures on the flow properties of bins is described and examples given for using the initial pressures to predict flow stoppages.

Pedagogy Of Hope

AbstractIn recounting the history of Cherbourg as an Aboriginal settlement, the Ration Shed Museum presents some traumatic narratives. It paints a picture of violent geographic and cultural dislocation, crude living conditions, forced labour and administrative oppression by infusing historical artefacts with the personal recollections of Cherbourg residents. The intent behind the Ration Shed Museum itself, however, is something quite different: its curators want to tell a story that speaks of hope for this community’s future, and to work towards some form of reconciliation. They do this by actively engaging with the ‘terrible gift’ of the past in the present, and by providing spaces for encounters that can lead to open discussions of difficult social issues and celebrations of contemporary Cherbourg life. This article draws on ethnographic interviews and observational data alongside the theoretical work of Roger I. Simon and Andrea Witcomb to describe how the Ration Shed Museum engages its community and visitors in a dual process of both understanding Cherbourg’s history and reframing traumatic narratives to enact a pedagogy of hope.

Turbomachinery Design

Progress achieved in numerical analysis during the past decade now permits the turbo-machinery designer to carry out a wide variety of inviscid, steady flow, two-dimensional calculations for compressible sybsonic and transonic flow fields, including some strongly diffusing flows. Three-dimensional (including viscosity) calculations are under development and should find wide spread use as analysis tools during the next decade. This review offers an introduction to recent advances in numerical turbomachinery design methods guided by the author’s design usage of several of the techniques reported.

The Past

It has become customary to begin a discussion of the nature and present state of the discipline of international relations with a number of complaints. This article will not abandon the custom; indeed, its purpose is, in the first place, to state the conviction that many of the problems we face in our field can be solved only by far more systematic theoretical work than has been done in the past—a conviction shared by most writers. Secondly, however, I will try to show that recent approaches to a general theory of international relations are unsatisfactory, because each one is, in its own fashion, a short cut to knowledge—sometimes even a short cut to a destination that is anything but knowledge.

Neutrally Buoyant

The steady flow of a suspension of closely fitting, neutrally buoyant, incompressible and elastic spheres through a circular cylindrical tube is investigated under the assumption that lubrication theory is valid in the fluid region. A series solution giving the displacement field of an elastic incompressible sphere under axisymmetrically distributed surface tractions is developed. It is found that, for closely fitting particles, flow properties of the suspension are strongly dependent on the shear modulus of the elastic material and the velocity of the particle.
