Euler number (physics)
From Wikipedia, the free encyclopedia
The Euler number or cavitation number is a dimensionless number used in flow calculations. It expresses the relationship between a flow's pressure and kinetic energy, and is used to characterize the potential of the flow to cavitate. It is named for Leonhard Euler.
It is defined as
where
- ρ is the density of the fluid.
- p is the local pressure.
- pv is the vapor pressure of the fluid.
- V is a characteristic velocity of the flow.
