WebThe main equations for compressible flow include the above continuity equation and the momentum equation from the Navier-Stokes equation. The main equation of motion is: In this equation, μ and λ are proportionality constants that define the viscosity and the fluid’s stress-strain relationship. The value of λ is generally a function of ...

If the flow is irrotational, then ∇ × v = 0. We can introduce a velocity potential, v = ∇ ϕ. Thus, ∇ × v vanishes by a vector identity and ∇ · v = 0 implies ∇ 2 ϕ = 0. So, once again we obtain Laplace’s equation. alma martinezWebApr 15, 2012 · Differential Equations - Flow Problem (Setting up the differential Equation) 9,986 views.
