we have a 10 kW FESS(flywheel energy storage system)
connected to a motor/generator and power electronics for wind
turbine
applications. we have two materials to choose from and their
dimensions and properties are given below.
(take the volume of the flywheel as the volume of the
cylinder)
calculate the maximum energy capacity of the flywheel at
its maximum angular velocity for both of the material
cases
The volumetric and gravimetric energy densities for both types of
material
Your company have the availability of two different flywheel materials, whose mechanical properties and rotor dimensions are summarized hereafter. Material l'in Tout H Density Max. tensile stress Shape factor Unit [mm] [mm] [mm] [kg/m3] [MPa] [-] Steel 0 670 550 7800 800 0.606 Graphite/epoxy 1.36 1.76 120 1600 1500 0.501 The friction losses associated to the bearing system and to the gas friction are 0.1% and 0.001% of the nominal power capacity.
