【Abstract】 On the basis of introducing the basic conception of Galerkin method,and with an example of Cartesian coordinate,the unsteady state heat conduction problem were solved and calculated using the finite volume method in structured grid.The results are in agreement when the approximate solution is compared with the numerical and the exact solutions.These prove that Galerkin approximating method is applicable to solve nonlinear heat conduction problem.更多还原
