摘要

The goal of this investigation is to study the effect of air injection on the wake development. As a widely commercial product, airfoil CFJ0025-131-196, is selected, and the profiles for velocity deficit, wake profiles for different attack angles, and profiles for change in the place where the velocity starts to increase are found. For the air jet velocity, the values of 0.0, 20.4, and 33.3 m s(-1) are examined while angles of attack are adjusted to 0, 6, and 14 degrees. The main flow speed is 10 m s(-1). It is found that when the dimensionless distance from the trailing edge goes up, the velocity deficit has a downward trend. Furthermore, the higher jet velocity is, the smoother the velocity deficit profile becomes. In addition, in a constant dimensionless distance, increasing the angle of attack results in growing the amplitude of the dimensionless velocity profile. The results also reveal that the location at which the velocity starts to increase moves down by the increase in the air jet velocity. Having a broad knowledge about the wake development of an airfoil will help to know its performance better and find more suitable ways to enhance its performance.
