Biography

Mahmoud is an Assistant Professor of Mechanical Engineering at Nile University in Cairo, Egypt, a Professional Mechanical Engineer, and a Subject Matter Expert in Vibration. He obtained his bachelor’s degree in mechanical engineering with honors from Cairo University and completed his doctoral studies at Ontario Tech University in 2019, specializing in fluid-solid interaction.

He has authored multiple research articles in scientific journals concerning solid mechanics, vibration, and fluid-structure interaction. His engineering expertise encompasses pipeline dynamics and stability, alongside the development of detailed analytical models for resonant vibration and noise generation in diverse structures. His research aims to improve empirical methods for predicting resonance and to design mechanisms that inhibit its negative physical consequences.

As a full-time faculty member at Nile University, Mahmoud manages applied research and industrial projects involving solid interaction with flows, with specific applications in power plant equipment and renewable energy. He currently serves as the Principal Investigator for a research project funded by the Egyptian Science and Technology Development Fund. Furthermore, his primary research focus includes the implementation of artificial intelligence agents in the development of mechanical engineering research tools.

To support the transition to green technologies, Mahmoud investigates vibration energy harvesting to engineer self-powered sensing methods for remote applications. His long-term research objective is to develop designs that mitigate vibration issues in sustainable technologies, guided by the flexible mechanics of biological species. Mahmoud currently teaches Solid Mechanics, Thermal Sciences, and other core undergraduate courses at Nile University.

The coupling between the shear layer separating between axisymmetric leading and trailing edges and the azimuthal modes of a cavity may result in self-excited spinning acoustic resonance. Notably, the spinning direction remains one of the less understood features of the coupled mode dynamics. In this work, compressible large eddy simulation is used to model the excitation of azimuthal acoustic

Corrosion constitutes a significant issue in industries that handle metals. Corrosion inhibitors with a low impact on the environment provide a significant economic benefit in various engineering applications. In this work, the effectiveness of olive leaves extract is evaluated as a cost-effective and environmentally-friendly corrosion inhibitor. The corrosion of carbon steel in different

In this work, the effects of adding hydrogen to diesel non-premixed combustion with air in a cylindrical furnace burner are investigated. A numerical model is developed to study the effects of hydrogen addition on combustion flame temperature and exhaust emissions. Different hydrogen addition ratios of 5%, 10%, 15%, and 20% by volume in the burning mixture are considered. The turbulence-chemistry

A Novel Prototype for Energy Harvesting from Low-speed Wind through Nonlinear Magnetically-assisted Galloping

Energy harvesting from low-speed wind offers a significant opportunity for applications such as remote sensing equipment and charging the batteries of small robots, during the night or underwater. These miniature devices require optimization to operate efficiently. There is a rapid growth in interest in these devices to serve the fast-growing robotics market. The development and optimization of an

Enhancing Heat Transfer in Heat Pipes through Controlled Vibration

Cooling electronic chips and hardware is essential to their safe and reliable operation. Heat pipes are devices that transfer heat between a source and a sink through a phase change process. In this project, the performance of the state-of-the-art heat pipe designs is enhanced through artificially created body force fields that are controlled by vibration and/or centrifugal rotation.

Cost-Effective Desalination by Falling-Film Freeze-Concentration with Minimal Environmental Impact

Water resource management is critical for sustainable social development in Egypt amid growing consumption and limited resource options. Recent national water plans have emphasized the strategic rule of nonconventional water supply through desalination. On the other hand, conventional desalination methods have a severe environmental impact due to increases in the temperature and salinity of the

Prediction of flow-excited acoustic resonance in coaxial burners

Abstract In this project, numerical analysis models acoustic modes in cavities. Different cavities with various aspect ratios are used. The square cross-section cavity created a spinning mode. However, a small change from the square configuration created an attenuation of the amplitude, which impacts the mode. More importantly, the shear layer changed according to the acoustic mode behavior such

Energy harvesting from vibrating flow devices

Abstract A square cylinder may gallop if subjected to fluid flow, experiencing a self-excited vibration mode that can harvest energy for low-power applications. The harvested power is typically low and depends on the upstream flow velocity and system dynamic parameters. In this project, the influence of nonlinear stiffness induced by two repulsive magnetic poles on the galloping response of square

Prediction and mitigation of common steam line hanger failures

Abstract Repeated hanger failures were observed in the steam condenser reject lines of a multi-unit nuclear power station, attributed to shear fractures of the threaded end of the hanger rods. The failures occurred at the same location in the piping run, near a reducer and an elbow where the stream flow changes direction. While condensed steam water slug impact is a possibility, the primary cause
