    Personal profile


    Ahmed is a Senior Lecturer of Thermal-Fluid Sciences in Mechanical Engineering, and his mainstream research is in sustainable & Zero-carbon heating and cooling technologies and heat storage. Ahmed has been undertaking research projects nationally and in collaboration with other countries (e.g., Rwanda, Kenya, Nigeria, Ethiopia, Ghana and Egypt) on these research topics. Ahmed is a Principal Investigator within the Energy and Bioproducts Research Institute (EBRI) and Aston Institute of Materials Research (AIMR) Centre at Aston University. His PhD/DPhil in adsorption cooling systems was awarded in December 2012. He has extensive first-hand research experience in thermal systems modelling and optimisation. He developed several adsorption/desiccant systems modelling approaches, which other researchers have widely adopted. He worked in 1D engine modelling to study and optimise the electrification of turbochargers, which also included 3D Computational Fluid Dynamic (CFD) turbine modelling and coupled 1D/3D-FCD modelling. Ahmed published several impactful journal research articles in highly reputable journals.
