During the friction of the steel pair, particularly when the dynamic load is high, the formation of the oxide layers is facilitated. These films cover the facing surfaces and play an important role in tribological behavior. ...

The present work is a numerical study of the three dimensional turbulent steady or unsteady flow, with or without heat transfer, of an incompressible fluid through a series of blades similar to those used in turbomachines. In ...

This thesis presents the results of two studies: the first concerns natural turbulent convection in a rectangular cavity heated from the bottom wall and filled with a nanofluid and the second relates to the investigation ...

Currently, intelligent systems are a rapidly developing field and booming. They have a major advantage: their adaptability to the environment, according to changing environmental conditions. In this context, there is a ...

The work presented in this thesis concerns the dynamic modeling of hybrid parallel robots. This work helps to solve one of the real problems of research on hybrid parallel robots that is to nd a compromise between a high ...

This thesis deals with the design, geometric, kinematic and dynamic modeling of bionic flexible robots. In particular, we are mainly interested in cable-driven flexible robots and a bionic robot named ‘‘Compact Bionic ...

The combination of the solar energy with a high fuel conversion cycle is one of the major advantages of hybrid concentrating solar systems compared to other solar power plants. This thesis seeks the design and the ...

We treat the problem related to heat transfer by natural convection through a three-dimensional numerical simulation study of two identical blocks heated and separated by a distance d, simulating the air cooling (assumed ...

This work presents a numerical study of natural convection in a laterally heated cavity filled with an electrically conductive fluid
