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 ...
Combined search for anomalous pseudoscalar HW couplings in VH(H -> b(b)over-bar) production and H -> VV decay
(Elsevier, 2016)
A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (= W or Z) in a sample of proton-proton collision events corresponding to an integrated luminosity of 18.9 fb(-1) at a ...
Parabolization and structural integrity of side bulb applied to a platform supply vessel
(DTU Mechanical Engineering, Technical University of Denmark, 2016)
The waterline parabolization is a hull form-optimization method, Calisal et al. (2002) reported a 10% decrease in the effective horse power at Fr = 0.275 for a coaster tanker. The present study was made for an oil platform ...
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 ...
