The results of an experimental study on axial dispersion in laminar flow of non‐Newtonian fluids through helical coils are reported. The ranges of variables covered are 10.5 ≤ λ ≤ 220, 0.6 ≤ n ≤ 1.0, 0.1 < N Regn < 140, and 0.04 < τ > 2.2. The condition for the applicability of Taylor's dispersion model is also reported. It is found that coiling results in a dispersion reduced over that in a straight tube.
