About
Overview
Dr Al-Zaili is a member of Turbomachinery and Energy Systems Research Group at City and the Programme Director for Mechanical Engineering. He worked in several engineering positions as design engineer, consultant, R&D engineer and project manager prior to joining City in 2015. Since joining City, he has been involved in a number of research projects, mainly in the field of small-scale gas turbines for renewable energy applications. His current research focus is on:
- Optimisation of micro gas turbines for solar power applications including thermal energy storage, operation and control;
- Low carbon microturbine-based propulsion system for small air vehicles;
- Aero-thermal design of small turbomachines;
- Impact of the distributed generation in large cities on the level of pollution;
- Pricing and market design for distributed generation and microgrids;
- High-temperature Modular compact thermal energy storage with focus on solar applications;
- Pollution reduction for combustion of hydrogen as a carbon-free fuel;
- The dynamics between low-carbon power technologies and supporting policies.
Dr Al-Zaili teaches postgraduate modules "Gas Turbine Engineering" and "Distributed Generation" and undergraduate module "Aerodynamics and Propulsion". He also delivers teaching sessions on Bioenergy for postgraduate students.
