We use explicit linear and implicit Euler finite difference schemes with a special time-steps formula to compute the blow-up solutions, and to estimate the blow-up times for three numerical experiments. Moreover, we calculate the error bounds and the numerical order of convergence arise from using these methods. Finally, we carry out the numerical simulations to the discrete graphs obtained from using these methods to support the numerical results and to confirm some known blow-up properties for the studied problems.</p>}, number={8}, journal={Iraqi Journal of Science}, author={Rasheed, Maan A. and Hameed, Raad A. and Obeid, Sameer K. and Jameel, Ali F.}, year={2020}, month={Aug.}, pages={2077-2086} }
