The method is a combination of Natural Transform Method (NTM) and Adomian Decomposition Method (ADM) which gives an exact solution. The exact solutions we obtained have been compared with the approximate solution of the nonlinear heat equations. ADM is able to solve this type of equations effectively and accurately without any need for discretization, perturbation, transformation and linearization.en-USNonlinear Heat EquationsAdomain Decomposition MethodNatural Decomposition MethodThesis
