Background
Dr Abdelrahman Abdeldayem is a Research Fellow in Mechanical Engineering at Cranfield University, specialising in thermofluids, turbomachinery, and experimental energy systems. His work focuses on the design, control, and testing of high-temperature supercritical CO₂ facilities for advanced power and heat transfer applications.
Abdelrahman holds a PhD in Mechanical Engineering from City, University of London, where he investigated aerodynamic losses and performance optimisation of large-scale axial turbines operating with supercritical CO₂ mixtures as part of the EU Horizon 2020 SCARABEUS project. His research integrates numerical modelling, experimental validation, and system-level analysis to improve the efficiency and reliability of future low-carbon energy systems.
Alongside his research, Abdelrahman has extensive experience in teaching and academic supervision. He has contributed to thermofluids education and laboratory development at City, University of London, and currently supervises postgraduate students in propulsion and power engineering at Cranfield. His teaching philosophy combines theory with hands-on experimentation, data-driven analysis, and student-centred learning.
He is an Associate Fellow of the Higher Education Academy (AFHEA) and serves as Deputy Director for Professional Development Courses at Cranfield, supporting the design and management of industry-focused short courses. Abdelrahman has authored numerous journal and conference publications and continues to pursue collaborative research that bridges academia and industry in the areas of energy conversion, turbomachinery, and supercritical fluid technologies.
Research opportunities
Dr Abdelrahman Abdeldayem’s research focuses on thermofluid systems, turbomachinery, and experimental diagnostics for energy and propulsion applications. His work bridges heat transfer and fluid dynamics with applied research in high-efficiency and sustainable power systems.
He specialises in the design and experimental investigation of supercritical CO₂ (sCO₂) power cycles, including the development and operation of high-pressure, high-temperature test rigs for component testing, control, and performance optimisation. His research also explores cycle integration for geothermal, solar, and waste-heat recovery applications, supported by advanced modelling and data-driven control techniques.
Abdelrahman is also developing flow visualisation techniques for studying fuel icing and for measuring mechanical strain and surface pressure on solid components using optical and image-based diagnostics.
Current activities
Dr Abdelrahman Abdeldayem is currently engaged in several projects that combine experimental research, advanced diagnostics, and numerical modelling. His ongoing work includes the development of flow visualisation techniques for fuel icing studies, enabling detailed observation of phase-change and deposition phenomena in fuel systems under low-temperature conditions. In parallel, he is advancing optical and image-based methods to visualise mechanical strain and surface pressure on solid components, supporting improved understanding of structural behaviour under dynamic loading. Abdelrahman is also contributing to turbomachinery design, modelling, and performance simulation for supercritical CO₂ applications, integrating CFD, thermodynamic analysis, and control strategies. These activities collectively aim to enhance the accuracy of predictive models and the fidelity of experimental data for next-generation energy and propulsion technologies.
