In an estuarine system, the flood tidal wave may become a tidal bore during the early flood tide in a narrow funnelled channel under large tidal ranges. Herein new experiments were conducted in a large flume to investigate breaking tidal bores and the bore roller propagation. The results demonstrated several key features of tidal bores propagating in rectangular channels. The propagation of the...

Accurate modeling of the acoustic propagation in tubes varying cross section musical acoustics must include effects viscous and thermal boundary layers. Models viscothermal losses are classically written frequency domain. An approximate time-domain model is proposed which all physical parameters instrument, bore shape or wave celerity, explicit coefficients. The depends on absolute tabulated co...

This study presents, experimentally, similarity and Froude number similitude (FNS) in the dimensionless features of two solitary waves propagating over a horizontal bed, using wave gauges high-speed particle image velocimetry (HSPIV). The have distinct heights H0 (2.9 5.8 cm) still water depths h0 (8.0 16.0 but identical H0/h0 (0.363). Together with geometric free surface elevation wavelength, ...

The relationship between tracer velocities and wave or wetting front celerities is essential to understand water flowing from hillslopes to the stream. The connection between maximum velocity and celerities estimated by means of experimental techniques has not been explored. To assess the pattern of infiltrating water front and dominant flow direction, we performed sprinkling experiments at a t...

Abstract Water wave propagation is one of the classical problems in free surface flow that involved water and air. There are a lot studies have been conducted on both experimental numerical methods. One method computational fluid dynamics (CFD), which divided into two major i.e. CFD mesh-based meshfree. In this paper, smoothed particle hydrodynamics (SPH) used to carry out study propagation. SP...

Abstract Hydroelastic responses of floating elastic surfaces to incident nonlinear waves solitary and cnoidal type are studied.

In this contribution, three methodologies based on temperature-sensitive paint (TSP) data were further developed and applied for the optical determination of critical locations flow separation reattachment in compressible, high Reynolds number flows. The rely skin-friction extraction approaches low-speed flows, which adapted work to study presence shock-wave/boundary-layer interaction. a first ...

This study is concerned with the generation and propagation of strongly nonlinear waves in shallow water. A numerical wave flume developed where solitary cnoidal types are generated by use Level I Green-Naghdi (GN) equations a piston-type wavemaker. Waves GN theory enter domain fluid motion governed Navier–Stokes to achieve highest accuracy for propagation. The computations performed two dimens...
