In order to analyze its effect, the three conservation equations are solved numerically by a predictor-corrector finite difference scheme and also by an improved characteristic method. A good agreement is noticed in comparison with others authors experimental and computed results. Beside this, approximate models of gas release rate are performed and compared by studying the diffusion phenomenaenGas ReleaseTransient HomogeneousFlow ParametersArticle
