Air entrainment and turbulent fluctuations in hydraulic jumps
- Hang Wang, H. Chanson
- Geology
- 18 August 2015
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, and… Expand
Experimental Study of Turbulent Fluctuations in Hydraulic Jumps

- 3 March 2015
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 substantial… Expand

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, but… Expand
Noncommutative Geometry and Conformal Geometry. II. Connes-Chern character and the local equivariant index theorem
- Raphael Ponge, Hang Wang
- Mathematics
- 13 November 2014
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 spectral… Expand
Noncommutative geometry, conformal geometry, and the local equivariant index theorem
- Raphael Ponge, Hang Wang
- Mathematics
- 7 October 2012
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 an… Expand
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 structures… Expand
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 stability… Expand
Turbulence and aeration in hydraulic jumps: free-surface fluctuation and integral turbulent scale measurements
- G. Zhang, Hang Wang, H. Chanson
- Physics
- Environmental Fluid Mechanics
- 1 April 2013
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 the… Expand
