Rate My Professor Abulnaser Sayma

Professor Abdulnaser Sayma serves as the Executive Dean of the College of Engineering, Design and Physical Sciences at Brunel University London since June 2024. He earned his BSc in Mechanical Engineering from Birzeit University in Palestine, MSc in Energy Technology for Developing Countries from the University of Salford, and PhD in Computational Fluid Dynamics from the University of Manchester Institute of Science and Technology (UMIST). His distinguished career includes leadership roles such as Head of the Department of Engineering at City University of London, Interim Dean of the School of Mathematics, Computer Science and Engineering, and Associate Dean for Postgraduate Taught Programmes at City University of London, as well as Director of Research for the School of Engineering and Informatics at the University of Sussex.

Professor Sayma's research specializations encompass the development of innovative turbomachinery designs and thermal power cycles for diverse temperature ranges. Key areas include low-temperature waste heat recovery via organic Rankine cycles, waste heat upgrading with heat pumps, intermediate-temperature power generation using supercritical carbon dioxide cycles, and high-temperature power production through Brayton cycles for micro gas turbines and gas turbines. He also advances technologies for thermal energy storage employing phase change materials across low, high, and ultrahigh temperatures. His PhD supervision covers turbomachinery design, analysis, and innovations in thermal power cycles such as gas turbines, organic Rankine cycles, supercritical CO2 cycles, and high-temperature heat pumps. Notable publications feature "A review of compressors for high temperature heat pumps" in Thermal Science and Engineering Progress (2024), "Aerothermal Investigation of the Effect of Endwall Riblets" (2025), "Supercritical CO2 power cycle control strategies: A review" (2025), "Design of micro-channel based actively cooled thermal shields" (2026), and several works on loss analysis and design optimization in radial inflow turbines and axial turbines for supercritical CO2 applications. With over 3,500 citations on Google Scholar, his contributions significantly influence the field of energy engineering.
