For many polymeric solutions in a simple shear flow a plot of the logarithm of the first normal stress difference N 1, against the logarithm of the shear stress a, for a range of temperatures results in a linear relationship. For such polymer solutions these plots yield a straight line of slope very
1980)). The predictions contain four scalar coefficients, given in terms of the viscosity ratio of the component fluids. In this work, experimental values of such coefficients were measured for the case of two Newtonian fluids in simple shear flow. The experiments were carried out in a parallel plat
