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 ...
Production and characterization of recycled polyester (r-PET) blend vortex and ring spun yarns
(Taylor & Francis Ltd, 2020)
Nowadays, many major fashion brands are now producing recycled polyester (r-PET) textile products from PET bottles to contribute to sustainability. Of course, this means that textiles containing r-PET will now be produced ...
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 ...
Effect of operational parameters on incremental forming of low-alloy sheet metals and its optimisation
(Taylor & Francis Ltd, 2021)
Incremental forming is a method with great forming potential. With this method, especially Low-Alloy Sheet Metals prototypes can be produced. Low-Alloy Sheet DC01, one of the metals, is widely used in the machinery industry. ...
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 ...
Predicting air permeability and porosity of nonwovens with image processing and artificial intelligence methods
(Taylor & Francis Ltd, 2020)
This study was conducted to investigate the relationship between the fiber distribution and the permeability properties of the hydroentangled nonwoven fabrics in terms of air permeability and porosity. The fiber distribution ...
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 ...
Z-symmetric manifold admitting concircular Ricci symmetric tensor
(Springer Heidelberg, 2020)
This paper deals with Z-symmetric Riemannian manifolds with concircular Ricci symmetric tensor. In the first section, we give an introduction of Z-symmetric manifold. In the second section, the definition of concircular ...
