A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...

The generation of noise by jets with highly disturbed laminar boundary-layer profiles at the nozzle exit, also referred to as initially nominally in literature, is investigated using large-eddy simulation and linear stability analysis. Four a Mach number 0.9 Reynolds , one nonlaminar profile three others profiles, are considered for exit peak turbulence intensities equal 6% case 9% ones. all ra...
