However, there is additional potential in the Open Method of Coordination that remains unexploited. Therefore the CREST-OMC needs to evolve to become a strategic learning and coordination policy instrument, rather than remaining a tool for the exchanging of information. This report suggests as well that the scope of OMC-CREST needs to be broadened beyond research issues, and points at a series of process-oriented improvements, all of which would raise the value-added of this policy instrument. On the basis of the above, this report puts forward a set of specific recommendations.
A new modification of the Danckwerts' exit boundary condition for the axial dispersion model ... more A new modification of the Danckwerts' exit boundary condition for the axial dispersion model is proposed. According to the novel boundary condition, the concentration gradient at the reactor exit is a fraction of the gradient predicted by the plug flow model. The fraction is a function of the Peclet number. A family of suitable function expressions has been derived. The
