Flywheel energy storage uses rotational inertia to store and release kinetic energy. It's used for power smoothing and peak shaving.

ସୂତ୍ର

Power = dE/dt (rate of energy change)

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Calculate: E = 0.5 × I × ω² where I is moment of inertia, ω is angular velocity
  2. 2Energy stored = change in kinetic energy
  3. 3Power = dE/dt (rate of energy change)

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Flywheel I=100 kg·m², ω=500 rad/s
ଫଳ
E = 0.5 × 100 × 500² ≈ 12.5 MJ energy stored
Significant storage capacity

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Neglecting bearings friction losses
  • Over-sizing flywheel (excessive cost and weight)

ବାରମ୍ବାର ଜିଜ୍ଞାସା

Why use flywheels over batteries?

Flywheels handle high power (charge/discharge rate); good for short-duration storage.

What limits flywheel speed?

Material strength; excessive speed causes material failure. Typically limited to 20-60% ultimate stress.
