Large Eddy Simulation of Supersonic Twin-Jet Impingement Using a Fifth-Order WENO Scheme
… flow field produced by supersonic twin-jet impingement is studied using a large eddy simulation (LES). The numerical model consists of two parallel axisymmetric jets of diameter 𝐷*, 3𝐷* apart, issuing from a plane which is at a distance H*=4𝐷* above the ground. The jet diameter 𝐷*, …

Numerical Simulations and Studies on Round Jet Impingement, Twin Jet Impingement and Helicopter Rotor Blades Ground Effect
… parts. The first part focused on single round jet impingement. The convention air jet impingement on ground surface was compared to air jet impingement on water surface in the range of Mach number from 0 to 0.3. Currently the studies on round jet impingement on water surface are very few. The …

Jet/Wall Interaction: An Experimental Study with Applications to VSTOL Aircraft Ground Effects
The flow field of a twin jet impinging on ground plane with and without free-stream and at low jet-height-to-diameter ratios was investigated using the Particle Image Velocimetry (PIV) technique. Detailed, time-averaged flow field data are obtained via the high-resolution and the high-sampling rate …
