WebNov 16, 2024 · lim t→∞ u(x,t) = uE (x) lim t → ∞ u ( x, t) = u E ( x) where uE(x) u E ( x) is called the equilibrium temperature. Note as well that is should still satisfy the heat equation and boundary conditions. It won’t satisfy the initial condition however because it is the temperature distribution as t → ∞ t → ∞ whereas the initial ... WebHere , we applied heat equation. The heat equation is given by: k ⋅ ∂ A 2 A 2 2 2 u / ∂ x A 2 = ∂ u / ∂ t. We need to solve this equation subject to the boundary conditions: u (0, t) = 0, u (L, t) = 0, and the initial condition: u (x, 0) = 1, 0 < x < L/2 =0, L/2 < x < L. To solve this problem, we first assume that the solution has the ...
