Pseudo Conharmonically Symmetric Spacetimes
(Univ Kragujevac, Fac Science, 2018)
In the present paper, firstly, the definition of pseudo conharmonically symmetric Riemannian manifold is given. In the second section, some theorems about these manifolds are proved. In the third section, pseudo conharmonically ...
Effect of Additive Level On the Surface of Diesel Engine Cylinder Liner
(Scibulcom Ltd, 2011)
In this research the surface of the cylinder liner was examined from metallurgical standpoints, using specimens cut from real engine component (single cylinder diesel engine liner operated 22 h), in order to identify the ...
A numerical study on squat of a wigley hull
(2011)
A numerical study is conducted to calculate the squat for a wigley hull. An approach based on slender body theory is used to convert the three dimensional ship problem into a series of two dimensional problems in cross ...
An integrated model for estimating energy cost of a tidal current turbine farm
(Pergamon-Elsevier Science Ltd, 2011)
A tidal current turbine is a device for harnessing energy from tidal currents and functions in a manner similar to a wind turbine. A tidal current turbine farm consists of a group of tidal current turbines distributed in ...
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 ...
Modeling of twin-turbine systems with vertical axis tidal current turbines: Part I-Power output
(Pergamon-Elsevier Science Ltd, 2010)
Recent interest in the tidal current industry has driven development of the prototype from the stand-alone turbine to the twin-turbine system. In this paper, we develop a numerical model to systematically analyze the ...
Estimating Power Output from a Tidal Current Turbine Farm with First-order Approximation of Hydrodynamic Interaction between Turbines
(Taylor & Francis Inc, 2010)
This article presents a numerical approach to estimate power output from a tidal current turbine farm with first-order approximation of hydrodynamic interactions between multiple turbines. An example study is conducted by ...
Numerical Study of Heat Transfer in A Porous Medium of Steel Balls
(Vinca Inst Nuclear Sci, 2019)
In this study, heat transfer in unidirectional flow through a porous medium with the fluid phase being water is analyzed using the commercial software Comsol((c)). The aim of the study is to validate the suitability of ...
A New Heat Transfer Correlation For Oscillating Fluid Flow
(Vinca Inst Nuclear Sci, 2018)
In this study, heat transfer under oscillating flow conditions has been investigated conducting a wide range of experiments using water as the flow medium. Experimental data have been reduced to obtain relevant heat transfer ...
