Main concepts

1. Circulation

   • Cantidades fisicas que ayudan a cuantificar la rotacion, vorticidad y circulacion

2. Stream function

   • Con la ecuacion
   • consideramos el flujo bidimensional

3. Velocity potential

   • irrotational flow are know as potential flows
   • 3D flows
   • irrotational flow

4. Laplace´s ecuation

   • Therefore, It is most fortuitous that incompressible, irrotational flow os described by laplace's equation

5. Vorticity

   • vorticity is a measure of the local rotation of the fluid

6. streamlines and path lines

   • In addition to knowing the density, pressure, temperature, and velocity fields, in aerodynamics we like to draw pictures of "where the flow is going" To accomplish this, we construct diagrams of pathlines and/or streamlines of the flow.
