Air entrainment and turbulent fluctuations in hydraulic jumps
A hydraulic jump is the sudden transition from a high-velocity impinging flow into a turbulent roller in an open channel. Substantial amounts of air are entrapped at the impingement point, andExpand

Experimental Study of Turbulent Fluctuations in Hydraulic Jumps
AbstractIn an open channel, the transformation from a supercritical flow into a subcritical flow is a rapidly varied flow with large turbulent fluctuations, intense air entrainment, and substantialExpand

Using small triangular baffles to facilitate upstream fish passage in standard box culverts
A culvert is a covered channel to pass streams and floodwaters through an embankment. The ecological impact of culverts has been recognised, in particular in terms of stream connectivity, butExpand

Noncommutative Geometry and Conformal Geometry. II. Connes-Chern character and the local equivariant index theorem
This paper is the second part of a series of papers on noncommutative geometry and conformal geometry. In this paper, we compute explicitly the Connes-Chern character of an equivariant Dirac spectralExpand

Noncommutative geometry, conformal geometry, and the local equivariant index theorem
We prove a local index formula in conformal geometry by computing the Connes-Chern character for the conformal Dirac (twisted) spectral triple recently constructed by Connes-Moscovici. Following anExpand

Experimental assessment of characteristic turbulent scales in two-phase flow of hydraulic jump: from bottom to free surface
A hydraulic jump is a turbulent shear flow with a free-surface roller. The turbulent flow pattern is characterised by the development of instantaneous three-dimensional turbulent structuresExpand

Defect solitons in parity-time periodic potentials.
In this article, properties of solitons in a parity-time periodical lattices with a single-sited defect are investigated. Both of the negative and positive defects are considered. Linear stabilityExpand

Turbulence and aeration in hydraulic jumps: free-surface fluctuation and integral turbulent scale measurements
In an open channel, a change from a supercritical to subcritical flow is a strong dissipative process called a hydraulic jump. Herein some new measurements of free-surface fluctuations of theExpand
