Abstract

Es importante entender las caracteristicas del flujo y el comportamiento de las velas tanto para los navegantes como para los disenadores que quieren tener un empuje eficiente de la embarcacion. En este trabajo, se presenta la simulacion del flujo de aire alrededor de las velas, con una geometria final impuesta, y con un codigo CFD reproduciendo las medidas a escala real. El codigo numerico utilizado es un CFD viscoso basado en las ecuaciones RANS. Se han considerado tres combinaciones de velas: dos mayores y una mayor mas genova y los parametros estudiados principalmente son la sustentacion, resistencia, centro velico y el coeficiente de presion sobre las velas. Se han comparado los resultados obtenidos con datos experimentales y otros datos numericos procedentes de otros estudios. El estudio concluye que hay una buena concordancia entre los calculos numericos y los datos a escala real, mostrando la importancia de la utilizacion de estas herramientas numericas. It is important to understand flow characteristics and performance of sails for both sailors and designers who want to have an efficient thrust of yacht. In this article, the airflow around yacht sails with imposed final geometry is simulated using a CFD (Computational Fluid Dynamics) code reproducing full scale measurements. The code is a commercial viscous CFD based on Reynolds-averaged Navier-Stokes (RANS) equations. Three sets of sails are considered: two mainsails alone and one set of mainsail with jib and the parameters in study are mainly the lift, drag, center of effort and pressure coefficient over the sails. The results are compared with both experimental data and numerical computations obtained from other studies. It is concluded that there is good agreement between numerical calculations and full scale data, showing the importance of the use of numerical tools.
