Article
Full-text available
This paper discusses the technical and economic feasibility of a renewable energy-based system, aimed to replace the traditional diesel engines implemented on a pushed and pusher bulk carrier barge. This barge has a challenging navigational route in the Nile River from Alexandria to Aswan and vice versa. It is scheduled to complete 30 trips annuall...
Article
Egypt depends on oil and gas for electricity generation (about 90%). The remaining small percentage comes from the hydropower of the High Dam (about 8%), the wind energy, and the solar cells. Therefore, it is important to adjust this unbalanced energy mix in Egypt. The continuous scientific research is the best way to try to solve this problem by s...
Conference Paper
Direct or inverse design methods for centrifugal pumps play an important role in investigating their performance. In this paper, a very low specific speed centrifugal pump impeller of ns = 9.5 (metric), three blades and 222° wrap angle. This pump was investigated using the direct design method to achieve the blade shape geometry and examine the bla...

Under and over filing for blade trailing edge are considered a common practice that is used to modify centrifugal pump performance. In this paper a three-dimensional simulation is presented to predict the effect of changing blade trailing edge profile on the performance of centrifugal pump of ns=9.5 (metric). Around 1,000,000 cells are used to solv...

In this work, the Lattice Boltzmann method (LBM) is used to simulate the fluid displacement processes of primary drainage and imbibition in a randomly generated heterogeneous porous medium. The present procedure is based on the single-relaxation-time Bhatnagar–Gross–Krook (BGK) approximation and the original Shan-Chen multi-component multiphase (MC...

The SUMED pipeline is a major oil transport pipeline in the Middle East. It provides an important route for transporting oil from the Arabian Gulf region to Europe and North America. The pipeline was subjected to major damage in the 1990s, which required the replacement of several kilometers at its peak point. Fluid hammer simulations using the met...
Conference Paper
This paper describes the Design, Engineering, Planning and Implementation activities that led up to an advanced, state of the art, optimum and economical solution for expanding an existing system to handle an increase of crude oil throughput from 80 to 117 mta metric tons per year (2.53 t/s to 3.71 t/s). The growing demand and reduced net imports o...
