This paper investigates a two-dimensional multi-term time fractional viscoelastic non-Newtonian fluid model using two autonomous consecutive spectral collocation strategies. A modified spectral approach is employed to obtain an approximate symmetric solution for the model, leading to an algebraic system of equations. Numerical examples demonstrate the effectiveness of the technique in terms of accuracy and convergence.
Applications of non-Newtonian fluids have been widespread across industries, accompanied by theoretical developments in engineering and mathematics. This paper studies a two-dimensional multi-term time fractional viscoelastic non-Newtonian fluid model by using two autonomous consecutive spectral collocation strategies. A modification of the spectral approach is implemented, leading to an algebraic system of equations able to obtain an approximate symmetric solution for the model. Numerical examples illustrate the effectiveness of the technique in terms of accuracy and convergence.
