Runge Kutta applied the problems one and two-dimensionals from the fluid mechanics

Abstract

Along didatic objectiv, presents the numeric solution of problems from the mechanics of the fluids by using the method Runge Kutta as of 4ª command about to solve us. This method that's a expansion of the Taylor's series , being the order from the Runge Kutta determined from the Taylor's series using derelict terms. Two case have been chosen for evaluating this method: (1) unidimensional problem, downfall of a body , being in this application compared the orders 1 to 4 from the Runge Kutta, to aiming demonstrate your efficiency , principally the one as of 4ª (2) a two-dimensional case,, launch of a bullet of cannon, being to solve by using Runge Kutta as order 4.
