The special case of unity dispersive Mach number of the hyperbolic axial dispersion model is investigated as the more realistic and simpler alternative to the parabolic model with zero Mach number. Simple corrections to the mean temperature difference or to the heat transfer coefficients are derived as functions of the dispersive Peclet numbers. As an example the model is applied to a cascade of stirred tanks in overall counterflow arrangement.
