Danckwerts boundary
WebA mathematical justification is given for the use of the “ Danckwerts ” boundary … WebThe boundary conditions normally associated with Equation (9.14) are known as the Danckwerts or closed boundary conditions. They are obtained from mass balances across the inlet and outlet of the reactor. We suppose that the piping to and from the reactor is small and has a high Re.

In practice, there are many models where the heat capacity is nearly constant, so the Inflow boundary condition behaves like a Danckwerts boundary condition with an averaged heat capacity. Interestingly, if this is … Webtion system which requires suitable boundary conditions at both ends of the reactor if the axial dispersion due to molecular diffusion and turbulence cannot be neglected. The boundary conditions often utilised are the so-called Danckwerts boundary conditions [4]. These conditions, however, have been somewhat controversial, because the hypothesis
