A comparison between the characteristics of fluid flows which were dealt with by classical mechanics of fluids and the features of complex materials presenting particular fluid properties subject to complicate conditions is performed. The fluids and their motion are analyzed and the mathematical models describing them are minutely shown. This analysis allows us to motivate why the most appropriate mathematical description of complex fluid flows must be the concern of thermodynamics of fluids. A parallel between the laminar and turbulent regimes of motion is also presented whereas the laminar/turbulent transition is associated with dynamics which at its last stages turns into a turbulent motion. In this way, an explanation of the transformation of perturbations into fluctuations is offered.
