A function of residence time distribution is derived by the method of generalized Heaviside series and an approximative procedure for the dispersion model coupled with ideal mixing boundary conditions, for "closed-closed" reactor, were used. Model is characterized by two parameters: Peclet number and volume fraction of the region of dispersion flow. The solution is studied numerically and the advantages of the approximative solution are discussed in detail.
