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 ...
Ibragimov-Gadjiev operators based on q-integers
(Pushpa Publishing House, 2018)
In this paper, we define the q-analogue of the generalized linear positive operators introduced by Ibragimov and Gadjiev in 1970. We study some approximation properties of these new operators, and we show that this sequence ...
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 ...
Yenilenebilir Enerjinin Gemilerde Kullanılması: Bir Yağ Barcına Kurulan Hibrit Sistemin Ekonomik ve Çevresel Analizi ile Optimizasyonu
(2019)
Artan enerji talebi, akaryakıt fiyatları ve fosil yakıtlardan kaynaklanan olumsuz çevresel etkiler, yenilenebilir ve sürdürülebilir enerjiye olan talebi artırmaktadır. Bu nedenle, rüzgâr ve güneş enerjileri günlük hayatta ...
Mathematical programming basis for ship resistance reduction through the optimization of design waterline
(Springer Japan Kk, 2017)
It has been more than a decade since Calisal et al. (J Ship Res 46(3):208-213, 2002) presented their concept of wave resistance reduction by allowing an increase in the beam of a ship accompanied by smoothing the shoulders. ...
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 ...
