Flywheel energy storage systems (FESS) can recover and store vehicle kinetic energy during deceleration. In this work, Computational Fluid Dynamics (CFD) simulations have been carried out using the Analysis of Variance (ANOVA) technique to determine the effects of design parameters on flywheel windage losses and heat transfer characteristics.
The main challenge facing flywheels is the high mechanical losses, such as bearing and windage losses (Amiryar and Pullen, 2020). Unlike the bearing loss, which is typically determined by factors such as flywheel weight and lubricant type, the windage losses can be reduced through modifications to the flywheel and the housing.
A vehicle’s kinetic energy can be recovered and stored in a flywheel energy storage system (FESS) (Erhan and Özdemir, 2021); therefore, optimisation of flywheel design is critical to the advancement of flywheel development and the reduction of emissions (Olabi et al., 2021, Choudhary et al., 2012).
