Thermal analysis of the friction stir welding process based on boundary conditions and operating parameters
Autor: Mouloud Aissani, David Bassir, Moustafa Boukraa, Tawfiq Chekifi, Nacer Tal Ighil, Nadhir Lebaal, Amina Mataoui
Publikováno v: Proceedings of the Estonian Academy of Sciences, Vol 70, Iss 4, Pp 516-523 (2021)
Modelling of friction stir welding (FSW) remains a complicated task, as it is crucial to predict the mechanical properties of the final welded part. This research focuses on the numerical simulation aspect of the alloy material AA2195-T8. 3D transien

Effect of the Aspect Ratio on the heat transfer enhancement by the Al2O3-H2O Nanofluid traversing a Heated Shallow Cavity
Autor: Chahrazed Abdellahoum, Amina Mataoui
Publikováno v: WSEAS TRANSACTIONS ON HEAT AND MASS TRANSFER. 17:104-113
In this work, the effects of the cavity aspect ratio (AR) on the flow of Al2O3-water nanofluid in a two-dimensional cavity subjected on its lower part to a constant and uniform temperature. The governing equations are discretized by the finite volume

Analysis of turbulent flow in a channel roughened by two-dimensional ribs: effect of first rib width
Autor: B. Omari, Abdelaziz Salem, Amina Mataoui
Publikováno v: Thermophysics and Aeromechanics. 27:45-59
This work investigates the turbulent flow in a channel roughened by seven ribs of rectangular cross section disposed transversely. The flow configurations of identical ribs from the first one generate a large eddy spreading along the top of the two f

Fluid flow of a wall jet impinging a hot obstacle
Autor: Malika KABACHE, Amina MATAOUI
Publikováno v: Journal of Thermal Science and Technology, Vol 10, Iss 1, Pp JTST0003-JTST0003 (2015)
A numerical study is performed in order to investigate the effects of the inlet flow structure on the flow and heat transfer characteristics in the reattachment zones over open cavity. Indeed, two inlet flow configuration are tested ; a turbulent wal

Effect of a Weak Jet on a Strong Jet
Autor: Amina Mataoui, S. Louaifi-Hamaili, Mohamed Aksouh
Publikováno v: Journal of Applied Fluid Mechanics, Vol 12, Iss 6, Pp 2083-2093 (2019)
This paper investigates the influence of a weak-jet on the development of a turbulent axisymmetric strong jet. A parametric study is carried out to evaluate simultaneously the effect to the jets-spacing (S/D=3 and S/D=7.5) and their velocity ratios i

Autor: F. Bentarzi, Amina Mataoui, M. Rebay, Grespi
Publikováno v: Journal of Applied Fluid Mechanics, Vol 12, Iss 2, Pp 403-411 (2019)
Journal of Applied Fluid Mechanics
Journal of Applied Fluid Mechanics, Isfahan Isfahan University of Technology, 2019, 12 (2), pp.403-411. ⟨10.29252/jafm.12.02.28964⟩
This study examines the interaction of twin oblique turbulent slot-jets of different directions (divergent, convergent or parallel) impinging a heated wall. A comparison of the results is done between the cases of perpendicular jets and three cases o
