  • Patent number: 6234014
    Abstract: The method of measuring the mixing efficiency in porous tubes comprising generating gas waves the composition of which at substantially constant total flow rate and pressure varies sinusoidal with time, causing said gas waves to flow through a section of said tubing from inlet to outlet, periodically sampling the gas waves in said tubing at a first point at the peak amplitude of the concentration of a first gas, sampling said waves at a second point at the peak amplitude of the concentration of a first gas, measuring the concentration of said first gas in said mixture in both said samples, and deriving and recording the difference in said concentration for each sampled wave, the difference of said concentrations at said peak amplitudes being a measure of the mixing efficiencies of said tube.
