WebThe Young-Laplace equation is a highly nonlinear PDE. We therefore require a good initial guess for the solution in order to ensure the convergence of the Newton iteration. In many cases good initial guesses can be provided by a simple, physically motivated continuation method. For instance in the model problem shown above, the computation Webstanding of the Young–Laplace equation. Manning1 refers to the basic thermodynamic derivation of the Young–Laplace equation. However, there exists also a mechanical derivation,5,6 the implications of which need to be understood. The normal stress balance for fluids meeting at an interface is DP = r n˜ = g H = g(1/R 1 +1/R 2) (10)

Equation (6.5.6) is a key equation which occurs when studying problems possessing spherical symmetry. It is an eigenvalue problem for Y(θ, ϕ) = Θ(θ)Φ(ϕ), LY = − λY, where L = 1 sinθ ∂ ∂θ(sinθ ∂ ∂θ) + 1 sin2θ ∂2 ∂ϕ2. The eigenfunctions of this operator are referred to as spherical harmonics. population of keithsburg il
