Abstract :
In this study, trigonometric cubic B-spline differential quadrature method
is developed for a linear transport problems constructed on the advection-diffusion equation. The weighting coefficients used in the derivative approximations are determined
by using the proposed algorithm. Following the space discretization of the advectiondiffusion equation, the resultant ODE system is integrated in time by using Rosenbrock
implicit method of order four. The accuracy and validity of the proposed method are
indicated by solving some initial boundary value problems (IBVPs) representing fade out
of an initial positive pulse. The error between the analytical and the numerical solutions
is measured by using the discrete maximum norm.
