Uniformly Convergent Numerical Method for Singularly Perturbed Two Parameter Time Delay Parabolic Problem

A Fitted Numerical Approach for Singularly Perturbed Two-Parameter Parabolic Problem with Time Delay

“…The authors in papers [21,22] developed uniform numerical methods for a singularly perturbed reaction-convectiondiffusion equation in one dimension with a discontinuous source term. In articles [23][24][25], the authors have developed robust numerical methods for singularly perturbed time delay parabolic problems with two parameters based on adaptive layer mesh methods. However, exponentially fitted difference (EFD) schemes have gained popularity as a powerful technique to solve boundary value problems.…”

Novel Numerical Scheme for Singularly Perturbed Time Delay Convection-Diffusion Equation

“…They treat the problems using fitted mesh techniques. Different authors in [16][17][18][19][20][21][22][23] developed numerical schemes using fitted mesh techniques for treating singularly perturbed parabolic time delay convection-diffusion equations. In [24], Podila and Kumar used nonstandard FDM for treating singularly perturbed parabolic time delay convection-diffusion equations.…”
