N2 - Using both Monte Carlo and numerical techniques, Taylor dispersion in a curved tube at low Dean numbers has been evaluated and the results are in qualitative agreement with those found by Janssen (1976): Dn2Sc is the controlling parameter with Detifalling to about 0.2 of its straight-tube value at high values of Dn2Sc. Agreement with available experimental data is generally good. Further, we find that for large Dn28c, the transition from convective to diffusive dispersion occurs earlier than in straight-tube flow, but only by a factor of two.
