WebAgain, setting λ = 0 gets us back to the typical form of Euler’s equations found in textbooks on inviscid flow. Bernoulli’s Equation. One useful relation for understanding incompressible steady flows is Bernoulli’s equation. This equation relates the energy (kinetic and potential) per unit mass of a fluid to its static pressure. WebPotential Flow Basics. Potential flows are those flow situations were the flow is taken to be irrotational, such that the vorticity is zero throughout the flow field (except at possible singularity points).
