• Abstract

  Several flows of practical interest are of viscoelastic fluids and it is often desirable to know if these flows are in a laminar or turbulent state. Although the hydrodynamics of viscoelastic fluids are strongly affected by the balance between inertia and elastic forces in the flow, the effect of elasticity on the stability of inertial flows has not been completely established. In this pr…

• Abstract

  The elliptic equations are partial differential equations and they are related to equilibrium problems that do not depend in general on time. The best known of these equations are the Poisson equation and the Laplace equation, whose applications are the most varied. The first represents the movement of a viscous incompressible fluid at low velocity and the second is employed to describe e…

• Abstract

  The elliptic partial differential equations have two equations that highlight for being the best known, the Laplace equation and the Poisson equation. The first equation has several applications in fluid mechanics, electromagnetism and astronomy, since the second equation for theoretical physics, electrostatic and mechanical engineering. The resolution of an elliptic equation by numerical…
