An Integrated Approach to Increase Marine Transportation Safety in Harbor Areas
(Marine Technology Soc Inc, 2017)
The importance of marine transportation safety in harbors and waterways access has become a very serious governmental concern in recent years, with the holding of special conferences on major marine disasters, increasing ...
Modeling of twin-turbine systems with vertical axis tidal current turbine: Part II-torque fluctuation
(Pergamon-Elsevier Science Ltd, 2011)
We recently showed the advantage of using a numerical system to extract energy from tidal currents by developing a new twin-turbine model (Li and Calisal, 2010a). Encouraged by this result, we decided to use this model to ...
On flow fluctuation's impact on the performance of vertical axis turbines-A potential flow analysis
(Amer Inst Physics, 2017)
During the last decade, with rapidly increasing deployment of tidal current turbine prototypes in many countries, a number of failures have been reported. Several of these failures were attributed to the intensive flow ...
Three-dimensional effects and arm effects on modeling a vertical axis tidal current turbine
(Pergamon-Elsevier Science Ltd, 2010)
Three-dimensional effects in studying a vertical axis tidal current turbine are modeled using a newly developed vortex method. The effects on predicting power output and wake trajectory are analyzed in particular. The ...
Numerical Investigation of the Effects of the Baffles Added in a Concentric Pipe Heat Exchanger
(Edizioni Ets, 2019)
In this numerical work, the effects of baffles added in a Concentric Tube Heat Exchanger are studied, using a commercial software CFD (Computational Fluid Dynamics) package. The CFD model is made to grab all the physical ...
Numerical simulation of transient heat transfer in friction-stir welding
(Edizioni Ets, 2018)
In this numerical study, three dimensional transient heat transfer analysis of Friction Stir Welding of two 8mm-thick AA-6061-T651 (an aluminum alloy) slabs has been performed. The numerical tool is the commercial package ...
Investigating the influence of tool shape during FSW of aluminum alloy via CFD analysis
(Chinese Inst Engineers, 2016)
This paper describes the application of the CFD code, Comsol Multiphysics, to modeling the 3-D metal flow in friction stir welding of AA 2024-T3 aluminum alloy in order to investigate the influence of tool shape over the ...
Comparison of Additive Protective Layer On the Cylinder Liner Surface Using Diesel Engine and Pin-On-Plate Test Rigs
(Scibulcom Ltd, 2011)
In this research, the layer formation of additives on the surface of cylinder liner (single cylinder Diesel engine liner operated 22 h) was examined by using binocular, optical, scanning electron microscope and energy ...
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 ...
