The velocity flow of an incompressible, inviscid fluid along a streamline is governed by Bernoulli’s equation. This equation describes the conservation of energy along a streamline in a steady flow of an ideal fluid, where no energy is lost due to friction or viscosity.
- V is the velocity at a specific point in the flow (measured in m/s).
- p∞ is the static pressure far away from the aerofoil or reference pressure (measured in N/m^2).
- p is the static pressure at the point of interest (measured in N/m^2).
- ρ is the density of the fluid (measured in kg/m³).
- V∞ is the free-stream velocity far away from the aerofoil or reference velocity (measured in m/s).
