NUMERICAL SIMULATION OF ENTROPY GENERATION FOR CASSON FLUID FLOW THROUGH PERMEABLE WALLS AND CONVECTIVE HEATING WITH THERMAL RADIATION EFFECT
In this work, the influence of entropy generation analysis for an electrically conducting Casson fluid flow with convective boundary conditions has been numerically studied. The governing equations are analyzed numerically using weighted residual methods. Subsequently, the residuals were minimized using two different approaches of weighted residual...

THREE-DIMENSIONAL SIMULATION OF A SMALL-SCALE ELECTRODIALYSIS PROCESS FOR DOMESTIC USE
The hydrodynamic by MHD driving force and ionic transport characteristics of an electrolytic solution in a small-scale electrodialysis process are taken into account in this new approach. A three-Dimensional modeling and simulation of coupling Magnetohydrodynamic-Ionic transport are carried out. The numerical values and the effects of applied volta...

BIOMECHANICAL BEHAVIOUR OF THE TOTAL HIP PROSTHESIS SUBJECTED TO NORMAL GAIT CYCLE LOAD: IDENTIFICATION OF THE DAMAGE IN THE CEMENT MANTLE
Cement is the weakest link in the composition of total hip prosthesis in terms of mechanical properties. The knowledge of the intensity and distribution of stresses on the cement attaching the implant to the bone is of great importance for understanding the condition of the prosthesis and its failure. In this study, the finite element method is use...

CONCEPTION OF A NEW GENERATION OF 3D BIOMIMETIC MICROVALVES FOR MEDICAL APPLICATION
This paper reviews the development of a new microvalve with a cone-shaped tube, inspired by venous valves in the human body. Our microvalves allow fluid flow in one direction while restricting the flow in the opposite direction. When a microvalve is used to control the amount of drug delivery, the efficiency between inlet and outlet flow rate is th...

A Proposed Damping Coefficient of Quick Adaptive Galerkin Finite Volume Solver for Elasticity Problems
A Quick Adaptive Galerkin Finite Volume (QAGFV) solution of Cauchy momentum equations for plane elastic problems is presented in this research. A new damping coefficient is introduced to preserve the efficiency of the iterative pseudo-explicit solution procedure. It is shown that the numerical oscillations are not only effectively damped by the pro...

Aerodynamic performances improvement of NACA 4415 profile by passive flow control using vortex generators
Improvement of the airfoil NACA 4415 aerodynamic performances by flow control using a passive technique was achieved in this study. Gothic-shaped vortex generators were added at the profile upper surface. Vortex Generators (VG) were used to avoid boundary layer separation at the profile trailing edge, thus reducing the drag force and improving aero...

Computational Analysis of Hip Implant Surfaces
During the total or partial hip replacement procedure, a damaged part of the hip joint is replaced with an artificial one. Both types of procedures include removal and replacement of the femoral head. After the femoral head is removed, an implant is inserted into the hollow femur. When the healing process starts, the newly formed bone interlocks wi...
