    Abstract: The aim of this paper is to investigate the interrogation area size effect on the hydrodynamic results of a stirred vessel equipped with an eight flat blades turbine. Particle image velocimitry (PIV) technique was used in order to compute the velocity field in the vessel. This PIV system is equipped with a Nd:YAG 532 nm laser, a CCD camera and a mi... Show More

    Abstract: Magnetic refrigeration is an emerging technology based on the magnetocaloric effect. In this paper, the magnetocaloric effect is remembered. The components of magnetic refrigeration system are described. An analogy between magnetic refrigeration and conventional refrigeration is done concerning the steps and the original work received by the system... Show More

    Abstract: In this paper, numerical simulations and experimental validation were carried out to gain an insight into the complex flow field developing around a small wind rotor and to evaluate its performance. We consider the Navier-Stokes equations in conjunction with the standard k-ε turbulence model to study the aerodynamic parameters of a NACA2415 airfoil... Show More

    Abstract: Gas turbine units are widely used in KSA and other countries particularly during the peak demands and in inland regions. They produce about 50% of the total capacity of power generation in the kingdom. Despite their numerous advantages, their thermal efficiency remains very low and their resulting environmental impacts are significant. In this stud... Show More

    Abstract: This work is dedicated to study numerically an inclined solar distiller subject of a moving cold wall. The cavity is heated from left side and cooled from the right one. Constant and different concentrations are imposed in the two vertical sides of the cavity, while the other walls are adiabatic and impermeable. The flow is considered laminar and c... Show More
