A dinâmica do sistema é construída em função da vorticidade e do vector de Lamb. Uma função correlação e a relação de dispersão foram analisados como função do número de Reynolds. Uma Lagrangeana para o vetor de Lamb e a vorticidade foi construída e as equações de movimento foram discutidas. Em seguida, analisamos a dinâmica para o caso de um fluido carregado. Por fim, introduzimos a generalização não-Abeliana de alguns resultados conhecidos. No apêndice, encontra-se uma breve revisão sobre fluidos não-Abelianos. / This thesis aims to obtain the Maxwell-type equations for a compressible fluid whose sources are functions of velocity and vorticity. A correlation function and the dispersion relation were analyzed as functions of the Reynolds number. A Lagrangian for the Lamb vector and the vorticity were constructed, and the equations of motion were discussed. After that, we have analyzed the case of a charged fluid dynamics. Finally, the non-Abelian generalization of some results was introduced. A basic review for non-Abelian fluids was described in the Appendix.
