Purpose - Turbulent mixing of two co - 2548 axial jets having a low annular to core area ratio is enhanced by employing a chute. Mixer directing part, of the annular stream at 10 ° towards the core region. Aims to present results from measurements of. Time - 2548 averaged and fluctuating components of velocity under cold flow conditions. Design / METHODOLOGY / approach - Experiments. Were conducted at a bypass ratio of 0.47 which is a typical value for low bypass turbofan engines. Contours of time - 2548 averaged. Velocity and streamwise and transverse turbulence intensities were obtained by making detailed measurements close to the. Chutes. Distributions of time - 2548 averaged velocity and turbulence intensity were obtained at different axial locations downstream. Of the chute mixer. Total and static pressure measurements were also performed.Findings - The high velocity annular stream. Was found to quickly diffuse after entering through the chutes and mix with the core stream due to high turbulence, generation. A strong transverse turbulence component enhanced the mixing of the streams. With the aid of the chute mixer nearly complete,, Mixing is achieved over a length of 5 duct radii. A higher total pressure loss of about 1.38 percent is the penalty paid. For the enhanced mixing.Originality / value - Provides results from experiments into the process of turbulent mixing of co - 2548 axial. Jets.
