Mily´s Essay

The topic of my reseach paper is "Flow of a Generalized Second Grade Fluid due an oscillating plate". It is about how a specific type of fluid (Second Grade Fluid) moves due the movement of a plate that supports the fuid. Basically, the idea is to give a process analysis about how t o obtain a mathematical expression that describes a physical phenomena (Second Grade Fluid's flow).

Most of the fluids that people know are called Newtonian Fluids, such air and water, they have a well-known behaivor and they have been studied for many years. However, there are other type of fluids, with different features, that have been gaining importance due their applications, such polymers, gels, emulsions, etc. The Second Grade fluid (SGF) could be used to describe the behavior of some polymers (often called viscoelastic fluids); however, that model has some restrictions for describing properly certain flows. In order to extend the applications of SGF model, there are some authors that have developed techniques to "Generalize" the model (improve its reults). One of those techniques is to modify the equation by replacing a derivative of an integer order by a Fractional Derivative (from Fractional Calculus, a specif area of Mathematics).

  1. Good work Mily! I don't know much about this subject so please keep defining those words for "non-specialized readers". You've done well here and I do understand the idea.
