Numerical Solution of the coupled Burgers' equation by Trigonometric
B-spline Collocation Method
Abstract
In the present study, the coupled Burgers’ equation is going to be
solved numerically by presenting a new technique based on collocation
finite element method in which trigonometric cubic and quintic B-splines
are used as approximate functions. In order to support the present
study, three test problems given with appropriate initial and boundary
conditions are studied. The newly obtained results are compared with
some of the other published numerical solutions available in the
literature. The accuracy of the proposed method is discussed by
computing the error norms L₂ and L_{∞}. A linear stability analysis
of the approximation obtained by the scheme shows that the method is
unconditionally stable.
