Notes:
An investigation into three dimensional fluid flow has been conducted which combinesthe use of Computational Fluid Dynamics (CFD) simulations with the experimental phenomenon ofStreaming Birefringence. A versatile flow channel was designed and built for use in conjunctionwith a circular polariscope. The experimental liquid used was an aqueous solution of a dye,commercially known as Milling Yellow NGS with the addition of Sodium Chloride. To extract theflow fields, six image phase stepping photoelasticity was used over backward and forward steps,and flows around a cylinder, and full-field fringe data were obtained. This method needs laminarflow regimes and the Reynolds number of the flow was around 10. To allow direct comparisons ofthe CFD solutions with the optical results, a macro (UDF) was written to interpret the flow fieldresults from a (FLUENT6) CFD simulation. This integrated the shear stresses across the flow fieldand banded the results into fringes. A good correlation between the simulated fringes and the shearstrainrate was obtained from these observations
