Cylindrical and rectangular hole geometries are used in the <br />experiments. The blowing ratio is 1.75, and the injection angle with respect to the horizontal <br />plane is 30o. The injection holes in the models are in a single row. The diameters of holes, <br />which have a cylindrical cross section, are 8.5 mm. The rectangular cross section holes are 9 <br />x 6.5 mm. The injection holes are inclined at 30o along the mainstream direction. The air is <br />injected at 57 oC and its blowing ratio is 1.75. The results show that turbulence intensity <br />changes with hole geometry. In this study, turbulence intensity is higher in the region close to <br />the wall because of the jet impact. The penetrations of the cylindrical jets into the main flow <br />are deeper than the penetrations of the rectangular jets, and turbulence intensities of the <br />cylindrical jets are larger than the penetrations of the rectangular jets. </p>}, number={3}, publisher={Gazi University}
