Phononic crystal surface mode coupling and its use in acoustic Doppler velocimetry
(Elsevier Science Bv, 2016)
It is numerically shown that surface modes of two-dimensional phononic crystals, which are Bloch modes bound to the interface between the phononic crystal and the surrounding host, can couple back and forth between the ...
Sharp bends of phononic crystal surface modes
(Iop Publishing Ltd, 2015)
Sharp bending of surface waves at the interface of a two-dimensional phononic crystal (PnC) of steel cylinders in air and the method of using a diagonally offset cylindrical scatterer are numerically demonstrated by ...
Low-concentration liquid sensing by an acoustic Mach-Zehnder interferometer in a two-dimensional phononic crystal
(Iop Publishing Ltd, 2015)
Mach-Zehnder interferometer formed by liquid-filled linear defect waveguides in a two-dimensional phononic crystal is numerically realized for sensing low concentrations of an analyte. The waveguides in the square phononic ...
Evanescent coupling between surface and linear-defect guided modes in phononic crystals
(Iop Publishing Ltd, 2016)
Evanescent coupling between surface and linear-defect waveguide modes in a two-dimensional phononic crystal of steel cylinders in air is numerically demonstrated. When the ratio of scatterer radii to the lattice constant ...
CFD based vortex generator design and full-scale testing for wake non-uniformity reduction
(Pergamon-Elsevier Science Ltd, 2018)
Propeller-induced vibration on ships may originate from separation and wake non-uniformity and can be dealt with stem form redesign, wake adapted propeller design or wake modification devices such as fins, ducts or vortex ...
Irreducible constituents of products of characters
(Taylor & Francis Inc, 2019)
In this article, we give some results about the relationship between the structure of a finite solvable group G and the kernels of irreducible constituents of the character where chi is an irreducible character of G. For ...
A Numerical study on the hydrodynamic performance of an immersed foil: Uncertainty quantification of RANS and SPH methods
(Pergamon-Elsevier Science Ltd, 2019)
The hydrodynamic characteristics of floating or immersed bodies may be evaluated by a variety of numerical techniques. Although these currently available techniques are well-established for providing valuable information ...
Evaluation of wind loads on ships by CFD analysis
(Pergamon-Elsevier Science Ltd, 2018)
Effect of wind loads on marine structures and ships has to be considered during design. Static and dynamic effects of wind forces and moments are incorporated into the rules and regulations of governing authorities by ...
Numerical Investigation of 2-D Wave Making Characteristics of a Submerged Hydrofoil
(2019)
In this study, 2-D wave making characteristics of a submerged hydrofoil has been investigated in a numerical fashion. Experimental data available for different depths of submergence and flow velocities have been compared ...
