Investigation of Jet Mixing Characteristics Using Slotted Rectangular Tabs
نویسندگان
چکیده
This article discusses the jet mixing effectiveness of rectangular tab with slots to distort jet, thereby creating vortices differing sizes enhance mixing. numerically investigates slanted slotted/perforated tabs slot connecting adjacent faces control Mach 0.4 jet. To intensify process, two similar equal blockage ratio 7% are placed at diametrically opposite locations convergent nozzle exit. The flow development in axial and radial directions investigated detail. measure slotted tabs, results compared free operated solid tab. percentage reduction core length obtained is 84.1 74% for employed tab, respectively, when exhibit that distorts near field a greater extent

Experimental Investigation of Jet Mixing Mechanism of Co-Flow Jet Airfoil
The jet mixing of a co-flow jet (CFJ) airfoil is investigated to understand the mechanism of lift enhancement, drag reduction, and stall margin increase. Digital Particle Image Velocimetry, flow visualization and aerodynamic forces measurements are used to reveal the insight of the CFJ airfoil mixing process. At low AoA and low momentum coefficient, the mixing between the wall jet and mainflow ...
متن کاملCharacterization of Multi - band Rectangular - Triangular Slotted Antenna
A multi-band microstrip patch antenna is developed and presented in this paper. The radiating elements in this antenna are composed of rectangular and triangular slots. These slots are engraved in the rectangular and triangular patch, joined together in one structure, and by single probe feed. The rectangular and triangular slots make the antenna to operate at multiband with relatively high gai...
