The main objective of this thesis is to study three-dimensional thermoconvective transfers in impact and channel jets using single and hybrid nanofluids (binary and ternary hybrid nanofluids) of different types and shapes. ...
This work presents a two-dimensional numerical study of the phenomena of mixed
laminar and turbulent convection in a ventilated square cavity. The geometry considered
consists of three blocks dissipating heat by Joule ...
This thesis's work contributes to the numerical study of mixed convection and entropy
generation in two different configurations filled with simple and hybrid nanofluids. Two
computational codes (Ansys-Fluent 18 and ...
The objective of this thesis is based on two different axes. The first is the study of the cracked
pipe due to internal pressure variation and the other is the benefit of a repair to improve the
life of the pipeline.
First, ...
Cracks can exist as a basic material defect or be created during fabrication or construction.
These cracks are responsible for the majority of failures that occur in structures such as
pipelines that are subjected to ...
The study carried out focuses mainly on numerical analysis by finite elements of the free
deployment of a standard airbag during a frontal collision. In this context, digital finite element
models have been developed to ...
The work undertaken in this thesis aims to establish new optimization and modeling approaches for hybrid solar installations (thermodynamic plants). Also, modeling was carried out on the main functional organs of this type ...
