Este trabajo presenta el modelamiento y evaluación de una contracción para un túnel de viento subsónico. Las simulaciones se realizaron a tres diferentes formas de contracción comúnmente utilizadas en túneles de viento, lo cual permitió a través de software tipo CAE analizar la uniformidad del fluido, turbulencia y el coeficiente de presión de a lo largo de la contracción. Estas simulaciones demuestran que la contracción propuestas por (Whitehead, Wu, & Waters, 1951) presenta un mejor desempeño en cuanto a las variables estudiadas. Con el objetivo de mejorar la uniformidad del fluido y disminuir su turbulencia en la salida de la contracción, fue utilizado un trip en la región de entrada de la contracción; lo cual mejoró en un 92,4% el coeficiente de presión y la intensidad de turbulencia.
