Abstract

In this paper we derive an integral formulation approach based on Greens function for the numerical solution of tubular reactor models described by reaction-diffusionconvection (RDC) equations with Danckwerts boundary conditions. The integral formulation approach allows the direct incorporation of boundary conditions and leads to a stable and accurate numerical integration with smooth round-off error. Numerical simulations on two models of tubular reactors are presented in order to illustrate the numerical accuracy of the method. Numerical solution is compared with standard finite difference method. Our results show that the integral formulation approach improves the performance of classical FD schemes.
