Waves generated by two or more ships in a channel
(2010-12-01)
The numerical model FUNWAVE+Ship simulates the generation and propagation of ship waves to shore, including phenomena such as refraction, diffraction, currents and breaking of waves. The interaction of two wave trains, ...
Propagation of ship waves on a sloping bottom
(2009-12-01)
The numerical model FUNWAVE was adapted in order to simulate the generation and propagation of ship waves to shore, including phenomena such as refraction, diffraction, currents and breaking of waves. Results are shown for ...
Asymptotic approach for the nonlinear equatorial long wave interactions
(2011-08-30)
In the present work we use an asymptotic approach to obtain the long wave equations. The shallow water equation is put as a function of an external parameter that is a measure of both the spatial scales anisotropy and the ...
Analysis of wave scattering from non-symmetric discontinuities in one-dimensional wave-guides
(2017-01-01)
Predicting the scattering from waves that are incident on a damaged section of structure is of importance in structural health monitoring and nondestructive testing techniques to detect dam-age. High frequency waves are ...
Water waves generated by local disturbance: Serre's model validity
(2002-12-01)
Water waves generated by landslides were long menace in certain localities and the study of this phenomenon were carried out at an accelerated rate in the last decades. Nevertheless, the phase of wave creation was found ...
Interaction between wave and coastal structure: Validation of two lagrangian numerical models with experimental results marine 2011
(2011-12-01)
Numerical modeling of the interaction among waves and coastal structures is a challenge due to the many nonlinear phenomena involved, such as, wave propagation, wave transformation with water depth, interaction among ...
Roll waves evolution in high gradient channels to a non-Newtonian rheology
(2002-12-01)
The criteria for the occurrence of roll wave phenomenon in the supercritical and turbulent Newtonian and non-Newtonian flows from the engineering point of view was analyzed. Imposing a constant discharge at the upstream ...
Wave transmission from asymmetrical changes of cross-sectional area in a beam
(2019-07-24)
In this paper wave scattering from an asymmetrical change of cross-sectional area in a beam is numerically studied. Incident symmetric and antisymmetric Lamb waves are considered and multiple wave mode conversion due to ...
Effects of macro and microstructure of aluminum alloy AA 6063-T6 with TIG-AC welding process with unbalanced rectangular wave
(2017-01-01)
The use of the rectangular wave in the TIG-CA welding process for aluminum alloys allows numerous possibilities of frequency control, wave amplitude variation and positive or negative current for the same wave cycle. The ...
The shock wave configuration used in nonlinear transmission lines to improve the voltage modulation depth
(2021-01-01)
Nonlinear transmission lines (NLTLs) using varactor diodes can produce high-frequency waves on the order of some tens of megahertz. They reach only low power signals, and a way to improve the voltage modulation depth (VMD) ...
