Since the beginning of the 1990s, a renewed interest for the thermoelectric appeared, due in particular to the emergence of environmental concerns regarding the gases used in refrigeration and emissions of greenhouse gases as well as the willingness…

Unilateral renal agenesis is a congenital malformation characterized by the complete absence of one kidney. Megaureters, on the other hand, are urinary tract anomalies characterized by abnormal dilation of the ureters, resulting in obstruction of…

In this study, a numerical analysis is carried out to optimize the pin fins heat sink (PFHS) performance. The investigation is conducted by using Comsol Multiphysics v.5.4 software based on the finite elements method (FEM). The effect of the…

This study focused on three-dimensional modeling of a specific tumoral process affecting the knee of a 30-year-old patient obtained by CT (computed tomography) using lower energy. To this end, we utilized the advanced digital software HOROS in…

Current internal combustion engines operate mainly on hydrocarbon-based fuel in the automotive transportation field. Their CO2 emissions are inevitable because they are a combustion product and greenhouse gases responsible for global warming and…

The present work is a numerical simulation of free convection heat transfer from H-shaped cross-section placed in square container. The work is accomplished by using the commercial code ANSYS-CFX. The studied parameters were the Prandtl and Rayleigh…

Energy consumption in residential buildings Algerian very high, especially during the summer season. A comprehensive approach to designing low-energy buildings reduces the size of mechanical systems to offset the additional cost of energy efficiency…

The solar chimney is a low-temperature power station generating electricity. The most important parameterizes the value of the air velocity along the chimney. A 3D numerical model is developed to estimate and analyze various parameters of the solar…

Low-grade heat from waste energy sources can be successfully recovered to produce power by an organic Rankine cycle. In the present work, reheat ORC is studied with three different wet organic fluids. The performance of R1270, R152a, and Cyclopropane…

Through this work, we want to evaluate the behavior of the fluid inside two successive chambers equipped with an opening for the fluid to enter the flow and the other for its exit. The fluid has a low temperature, while the lower wall of the two…
