A technique is described for the design of a test signal such that the parameters, defined by the axial mixing model for a packed tower, can be estimated with the greatest accuracy from experimental records. Methods for calculating the effect of additive noise, usually associated with small amplitude signals, on computed correlation‐, spectral‐and amplitude ratio estimates are discussed. Designed experiments were performed on a 10‐in. I.D. packed tower by the injection of a radioactive tracer into the gas phase. Peclet numbers for both dry and irrigated beds are reported.
