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 Degree in Mechanical Engineering with honors at Cairo University and completed his doctoral studies at Ontario Tech University in 2019 with a specialization in fluid-solid interaction. Mahmoud authored several research articles in leading scientific journals in the subjects of solid mechanics, vibration, and fluid-structure interaction. He develops detailed models for resonant vibration and noise generation in various structures. His research aims to improve empirical methods to predict occurrence of resonance and explore novel designs to inhibit its negative consequences. As a full-time faculty at Nile University, Mahmoud continues to work on several research and industrial projects that involve solid interaction with flows, with applications in power plant equipment and renewable energy. To help achieve transition into green technologies, Mahmoud explores promising technologies for vibration energy harvesting to develop self-powered sensing methods a wide range of remote applications. His long-term research goal is to develop biologically-inspired designs to address vibration issues in sustainable long-standing technologies as well as advance the development of innovative environment-friendly technologies guided by the flexible mechanics of biological species. Mahmoud currently teaches Solid Mechanics and Thermal Sciences among other courses to undergraduate students at Nile University.

Research Project

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

Research Project

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. Objective

Research Project

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

Research Project

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

Research Project

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

Research Project

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
