Basic equations (3)
For a two-dimensional flow, write the Continuity equation and the Momentum equation for a real fluid in the Cartesian system of coordinates. What is the name of this equation?
Does the above equation apply to any flow situation? If not for what type of flow field does the equation apply for? Write the above equation in a polar system of coordinates. For a two-dimensional ideal fluid flow, write the continuity equation and the Navier-Stokes equations (in the two components) in Cartesian coordinates and in polar coordinates.
