Se discuten los resultados al variar el orden en el que se truncan las series y se comparan con resultados conocidos.ĭescriptores: Número de Reynolds bajo Eqs. Estas últimas se resuelven usando series de Fourier, en la variable angular, y series de potencias en R e esto con el fin de estudiar algunas características generales. Las condiciones de frontera sobre el cilindro se satisfacen de manera trivial y la condición al infinito resulta en un sistema de dos ecuaciones diferenciales ordinarias no lineales. Las soluciones en series de potencias en x, dan pie a tres relaciones de recurrencia entre sus coeficientes, de los cuales, solo dos son independientes. El procedimiento esta basado en una transformación en la coordenada radial, de manera que la nueva variable (x) queda definida en un intervalo finito. Se propone un método de soluciones en series, que se truncan para obtener soluciones aproximadas al problema del flujo alrededor de un cilindro. Keywords: low Reynolds number stationary Navier-Stokes eqn's slow viscous flow series truncation flow past a cylinder drag coefficient. Results on the convergence of the series, with varying order of truncation, and comparison with earlier results are discussed. These are solved using Fourier series in the angular variable and, for the sake of argument, in a power series in R e. The boundary conditions on the cylinder's surface are satisfied in trivially way, and the conditions at infinity lead to a system of two non linear ordinary differential equations. Solutions are truncated power series in x, so that the full Navier-Stokes equations are transformed into three recurrence relations with two independent coefficients. This procedure is based on a change in the radial coordinate (x), such that this new coordinate is defined in a finite interval.
