| Abstract: | It is usually not an easy matter to analytically solve a partial differential equation problem subject to certain given initial and boundary conditions. Although numerical approaches may help, the method of perturbation expansion, even in a truncated form of only two terms, provides an alternative approach and better insight to solve the problem analytically. In addition, the perturbation method usually offers a clearer physical picture to the problem. When a suitable perturbation expansion is applied to a fluid flow, boundary layers close to solid walls will be considered, if some physical quantities are expected to change rapidly. By matching the solution with the boundary conditions, a solution valid throughout the entire region can be found. The following work shows how perturbation method being applied to a real life problem: a heat conduction and convection flow, with different initial and boundary conditions. |
