WebJul 9, 2024 · The transient solution satisfies v(x, 0) = f(x) − w(x). Finally, the initial condition gives u(x, 0) = w(x) + v(x, 0) = w(x) + g(x). Thus, if we set g(x) = f(x) − w(x), then u(x, t) = w(x) + v(x, t) will be the solution of the nonhomogeneous boundary value problem. We all ready know how to solve the homogeneous problem to obtain v(x, t). WebDec 6, 2024 · Initially, the cylindrical fin is in equilibrium with the surrounding fluid, that is, t=0: u (r, z, 0)=0.
