DEL RIO, J.A.  e  CASTREJON PITA, J. R.. Modelo simple para la permeabilidad dinámica de fluidos viscoelásticos. Rev. mex. fis. [online]. 2003, vol.49, n.1, pp.75-86. ISSN 0035-001X.

In the present work a simple form to obtain analytical expression for the dynamic permeability of Maxwellian fluids is presented. This expression gives the frequency dependent form of this dynamic permeability. In particular case, the analytic expression for the sinusoidal pressure pump fluid is illustrated in the configuration space. As an example of the feasibility of this expression the flow of human blood in a tube is presented finding that the human heart frequency has the same order that the frequencies where the dynamic permeability shows resonances. In order to make clear the above aspect of the dynamic permeability a model of pulsing pressure drops (gaussian like) are analyzed.
