Abstract:
A transparent viscoelastic blood analog fluid was developed for use with Laser-Induced Photochemical Anemometry. To provide solubility of the photochemical tracer, 1', 3', 3'-trimethyl-6-nitroindoline-2-benzopyran (TNSB dye, Kodak Chemicals), the analog solvent needed to be nonpolar, thus currently available aqueous blood analogs were not suitable. An analog consisting of 0.04% ethylhydroxyethylcellulose dissolved in gamma-butyrolactone produced a pseudoplastic steady shear response with low elasticity in unsteady shear, while being compatible with the photochemical tracer.
