There is a and their macros f Stat complex geo n this and rheology. We d model, wher of th Molecular D ctan of a solution. The flow curve for this particular system, using a mean field scaling relationship. Finally, as our motivation in this work is to understand the flow of wormlike micellar fluids in porous media, we give preliminary experimental results for the flow in an expansion-contraction capillary using micro Particle Image Velocimetry (-PIV). This demonstrates the complex response of these fluids in non-viscometric flows and the challenges they pose to any predictive simulation model
