ANALYSIS OF RHEOLOGICAL MODELS OF NON- NEWTONIAN FLUIDS

In this paper, an attempt has been made to analyse the development of non-Newtonian fluid from the classical theory of Newtonian liquid. Various rheological models of constitutive equations of different kinds of non-Newtonian liquid have been discussed. Development of the theory of non-Newtonian fluid overcoming the limitations of classical theory of perfect fluid has been discussed in detail. Classifications of visco-elastic as well as visco-inelastic fluids are also analysed.
