The investigation of synthetic jet vortex rings flowing through a honeycomb is measured by two-dimensional particle-image velocimetry. established using free jets generated piston–cylinder apparatus upstream the honeycomb. On that basis, turbulence obtained at circulation Reynolds numbers ReΓ = 3437, 5155, 6874, and 8592, Resj 561, 841, 1121, 1402. effects diameter number (ReM 41–449) length-to...
