This study presents a comparative analysis of slow pyrolysis applied to sugarcane bagasse from the Kenana Factory in Sudan and corn stover, focusing on biofuel production potential. Experiments were conducted with a heating rate of 0.9 °C/s, raising temperatures from 255 °C to 686 °C over a 50-min residence time. The results show that corn stover a...
This study investigates the use of a saltwater (sodium chloride and water) solution as a phase change material (PCM) in a small fridge for storing scorpion antivenom in Sudan's northern state. The experimental results demonstrate the effectiveness of the PCM in maintaining suitable storage temperature which 3 ± 2°C. By adding salt to the water, the...
In recent years, the shift in interest from fossil fuel-based power generation to renewable energy has led to a significant increase in the use of photovoltaic (PV) technology. Therefore, studying its performance is a priority in research in the solar energy field. The Kingdom of Saudi Arabia is notable for its vast area and contemporaneous climate...
Heat exchangers are devices whose primary responsibility is to transfer heat, typically from one fluid to another. In such applications, the heat exchangers can be parallel flow, crossflow, or counter flow. An essential part of any heat exchanger analysis is the determination of the effectiveness of the heat exchanger.In the present work, three dif...

The aim of present work is to investigate the performance of photovoltaic modules (PV) influence by wind speed and direct solar irradiance in Saudi Arabia. These two parameters have a significant effect on the performance of PV module. In the present work experimental set up, one unit of the PV module was examined with change of wind speed and dire...
The purpose of this work was to perform a thermal–hydraulic numerical analysis of a nanofluid as the coolant in a typical MTR (material testing reactor) core. Numerical simulation was carried out for turbulent flow of water based nanofluid of different concentrations of Al2O3 nanoparticles through a sub-channel of a typical MTR core subjected to co...
In the present work, three dimensional CFD analysis is presented for a typical MTR reactor coolant loop during natural convection cooling regime. Design optimization studies are carried out. A model consisting of the core, the chimney, and the cold legs is simulated. The research reactor core is simulated as a porous zone with a cosine shape heat d...
A three-dimensional study of steady laminar natural convection in partially top vented enclosure is investigated numerically. A discrete heat source mounted on the substrate at the bottom wall is used to simulate an electronic component. Three types of heat source are used with vent aspect ratio ranging from 0.0 to 0.1. The problem is described by...
The number of investigations on convective heat transfer through a packed bed has been on the rise during the past decade. Many thermal engineering systems are in need of a better understanding of forced convection through packed bed. Such applications include: compact thermal collector-storage systems, drying processes, heat exchangers, grain stor...

ARTICLE INFO ABSTRACT A three investigated numerically. A discrete heat source mounted on the substrate at the bottom wall is used to simulate an electronic component. Three type ranging from 0.0 to 0.1. The problem is described by continuity, momentum and energy partial differential equations, which are expressed in Cartesian coordinates system. T...
In the present study incompressible, viscous, and turbulent flow of water through a butterfly valve of 20 cm diameter was considered. The aim of the present study was to provide comprehensive study of the effect of inlet velocity on the variation of flow characteristics with valve positions. For this purpose, different values of inlet velocity of 1...
In The present work the heat transfer and flow characteristics for the case of natural convection inside air filled cavities were studied numerically under steady state conditions. Two cases were studied. The first case was of closed cavities, in which the effect of Rayleigh number (Ra), and aspect ratio on heat transfer and flow characteristic ins...
Modeling and simulation are very powerful tools and have become an integral part in the design and development of engineering systems. The objective of this research is to develop a computer program to simulate water hammer oscillations in a single pipe line. A mathematical model has been developed to simulate water hammer in one dimensional single...
In this study a mathematical model has been developed to simulate two dimensional fluidized beds with uniform fluidization. The model consists of two sub models for hydrodynamic and thermal behavior of fluidized beds on which a FORTRAN program entitled (NEWFLUIDIZED) is devolved .The program is used to predict the volume fraction of gas and particl...
