A finite-difference procedure is employed to predict the development of turbulent flow in curved pipes. The turbulence model used involves the solution of two differential equations, one for the kinetic energy of the turbulence and the other for its dissipation rate. The predicted total-velocity contours for the developing flow in a 180’ bend are compared with the experimental data. Predictions...

We show uniqueness of Ricci flows starting at a surface of uniformly negative curvature, with the assumption that the flows become complete instantaneously. Together with the more general existence result proved in [10], this settles the issue of well-posedness in this class.

In this work, the stability of hypersonic flow over a curved compression ramp is studied using several analysis tools and direct numerical simulations (DNS). The free-stream Mach number unit Reynolds are 7.7 $4.2 \times 10^6$ m $^{-1}$ , respectively. Corner rounding considered to alter separation bubble so as suppress intrinsic instability compression-ramp flow. variation confirmed by global a...

The Moving Pictures Show is a contemporary Australian ‘silent’ film company that screens films produced in the period from 1912 to 1929, with a 9-piece orchestral accompaniment. This article explores the ways in which music is chosen for the show both to heighten the audience’s aesthetic experience of the film and to abide by historical practice. It also describes the ways in which improvisatio...

In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved le...

Four species of the genus Haplosyllis from Indonesia are herein described and illustrated. In Haplosyllis aciculata sp. nov. and Haplosyllis ingensicola sp. nov. the longest midbody cirri exceed body width and posterior parapodia have a single broad, strongly curved acicula, while in Haplosyllis tenhovei sp. nov. and Haplosyllis nicoleae sp. nov. cirri are shorter than body width, and the two o...
