Abstract
A procedure to study tracer dispersion was proposed and tested for the case of tracer spreading in tube flow. Concentration maps of paramagn etic tracers Gd3+ were measured in time through direct measurements of spin lattice relaxation time T-1 obtained by using a two-point stimul ated echo pulse sequence. The procedure was used to test the linear de pendence of Peclet number on inverse velocity in the range of dow rate s 0.3-1.2 cc/min. (C) 1998 Elsevier Science Inc.
