This Bachelor’s Degree Thesis consists on a computational study of non-viscous andviscous fluid flows interacting with different external conditions and solid objects.The governing equations of fluid dynamics are Navier-Stokes equations. NS equa-tions are differentiate partial equations that are transformed into numerical expres-sions that can be computed.Simulations with the computer are runned for different reference cases for which aprevious solution has been obtained analytically or by researchers, beforehand.The principles, solvers and methods used to achieve a solution for the simulationscan be extrapolated to more complex problems.
