Paper Abstract

We report on the use of phase-resolved DOCT to measure oscillatory flow in a rigid glass capillary. Experimental measurements are obtained in which a sinusoidal pressure gradient generates a sinusoidal varying flow of a scattering liquid (Intralipid-20%) in a 660 micron i.d. glass tube. Dynamic flow profiles are measured and compared with the analytical theory due to Womersley. Reasonable agreement is found for one half of the flow profile (-ve velocities) but the agreement is less good for the +ve velocities. Possible reasons for the discrepancy are discussed. The study indicates the usefulness of DOCT for studying fluid flow dynamics.
