Abstract
The current project consists on the design of a numerical model to solve the steady streaming that is produced when an oscillating flow faces solid cylinders. This model was created by using finite element modelling techniques through the use of Freefem++ software. The development of the code to solve the flow involves the implementation of the Navier-Stokes equations and the creation of a mesh, which define the geometry of the problem. Three different geometries are presented. The first one consisting on one single cylinder in the middle of the microdevice, the second geometry consists of two cylinders positioned side by side separating by a distance ga, and the last one consist of four cylinders, two of them positioned in the x axis and the other two positioned in the y axis. In this last geometry some parameters, that define the geometry, are modified, to see how is affected the resultant flow.
