Abstract

PARA ROMPER LAS TURBULENCIAS EN UNA SUPERFICIE (9) RODEADA POR UN FLUJO TURBULENTO TANGENCIAL, UNA PARED (11), SITUADA EN PARALELO A UNA DETERMINADA DISTANCIA (12) DE LA SUPERFICIE CIRCULADA, SE DOTA DE ELEMENTOS ESTRUCTURALES DISPUESTOS PERIODICAMENTE. LA DISTANCIA (12) DE LA PARED (11) A LA SUPERFICIE RODEADA POR EL FLUJO DETERMINA EL TAMAÑO MAXIMO TOLERADO DE LAS TURBULENCIAS Y LAS MEDIDAS Y DISTANCIAS ENTRE LOS DIFERENTES ELEMENTOS ESTRUCTURALES CORRESPONDEN A LA MAGNITUD DE LA DISTANCIA ENTRE LA PARED Y LA SUPERFICIE CIRCULADA.
