Proc. ASME. GT2022, Volume 6B: Heat Transfer — General Interest/Additive Manufacturing Impacts on Heat Transfer; Internal Air Systems; Internal Cooling, V06BT15A003, June 13–17, 2022
Paper No: GT2022-79362
... Abstract This paper presents an experimental investigation of heat transfer and pressure loss for leading edge jet impingement using racetrack shaped jets. The majority of literature considers jet impingement using square, or sharp edged orifices, to create the jets. However, for gas turbine...

... involved in jet impingement cooling shape [15], nozzle aspect ratio [16], target surface modification such as, exit orifice shape, crossflow regulation, target surface [17], and many more. Some common examples of orifice shape modification, spent air reuse, impingement channel modification are triangular...

... in two regions: impingement and crossflow. In the presented work, both plates with identical inline arrays of (20 × 26) circular air jets impinging orthogonally on a flat target comprised of 20 segments parallel to the jet orifice plates, are studied. The first is a staggered configuration of a pimple...
