    • Development of a CFD Model for the Estimation of Windage Losses Inside the Narrow Air Gap of an Enclosed High-Speed Flywheel 

      Eltaweel, Mahmoud; Kalyvas, Christos; CHEN, Yong Kang; Herfatmanesh, Mohammad Reza (Springer Nature, 2023-08-12)
      Concerns over global warming and the need to reduce carbon emissions have prompted the development of novel energy recovery systems. During urban driving, a significant amount of energy is lost due to continuous braking, ...

    • Numerical analysis of a flywheel energy storage system for low carbon powertrain applications 

      Motaman, Shahed; Eltaweel, Mahmoud; Herfatmanesh, Mohammad Reza; Knichel, Tobias; Deakin, Andrew (2023-02-11)
      Flywheel energy storage has emerged as a viable energy storage technology in recent years due to its large instantaneous power and high energy density. Flywheel offers an onboard energy recovery and storage system which ...
