| چکیده | ||
| This study presents a hybrid numerical framework that combines the enhanced moving least squares (MLS) approximation, neural networks, and spectral methods to solve a fractional-order electrohydrodynamics flow model in a cylindrical conduit. The proposed method transforms the governing problem into a nonlinear system of algebraic equations. The enhanced MLS technique facilitates the construction of smooth approximations for scattered or irregular data distributions, while the neural network component provides a flexible mechanism for modeling the nonlinear and memory-dependent behavior inherent in fractional-order systems. By embedding MLS-based shape functions as activation mechanisms, the framework effectively captures the solution. Furthermore, a collocation strategy based on the roots of the Legendre polynomials is employed to minimize the residual associated with the underlying fractional operator. This approach improves numerical accuracy and robustness, as verified by the convergence analysis provided in this study. To show the effectiveness of the proposed method, some numerical results are provided. | ||
