Numerical solution for 2-Dimensional, steady-state, temperature distributions in a flat plate with 3 edges at a fixed temperature and one edge in Convection. Base Line - Exact solution of simpler case found analytically. Modeling and validating the numerical solution (Fortran). PROBLEM STATEMENT
MODELING A SYSTEM • Partial Differential Equations used to model the system. • Finding the temperature values at a finite number of points characterized by mesh.
FINITE DIFFERENCE APPROACH Heat flows vertically and horizontally into node of interest.
Gauss-Seidel (near-neighbor) sweeps to convergence. Interior n-by-n points updated in each sweep according to the formula: ITERATIVE SOLUTION (Gauss-Seidel) • Updates done in-place in grid, and residual value computed. • Check if error has converged (to within a tolerance parameter). • If so, exit solver; if not, do another sweep.
