- Influences of Nozzle Aspect Ratio and Orientation on Flow Characteristic of Multiple Elliptic Jets
抄録
<p>The present paper reports on an experimental investigation of the mixing and development process of multiple elliptic jets with 6×6 square matrix nozzles arrangement at a Reynolds number of 4.0×103. The multiple elliptic nozzles for aspect ratios of a/b = 2.25 and 6.25 were arranged with the same and the alternate azimuthal orientations. The flow field was measured using the X-type hot-wire probe. The development process of multiple elliptic jets was visualized by the contours of mean and fluctuating velocities at the y-z cross-sections. The multiple elliptic jets merge into a single square jet flow, and the merging point depends on the equivalent diameter. In the case of multiple elliptic jets for a/b = 6.25 with the alternate azimuthal orientation, the axis-switching phenomenon does not occur in the downstream due to the secondary flow induced by the entrainment.</p>
