Results for inverted veloCalculations jets indicare that relative mademum instability wave amplitudes and for field peak noise levels can be reduced from thet of the reference jet by having higher stability rates for the outer shear layer, low velocharacteristics outer streams hotter than the inner stheam.
Results for inverted velocity profile jets indicate that relative maximum instability wave amplitudes and far field peak noise levels can be reduced from that of the reference jet by having higher spreading rates for the outer shear layer, low velocity ratios and outer streams hotter than the inner stream.
Their controlling influence on sound emission at low Mach numbers, with the influence of acoustic feedback on their development, are both illustrated with specific reference to jet noise, engine breathing noise, plant noise and the voicing of vowels.
These topics are discussed with reference to jet grouting applications in the construction of the cut & cover tunnels at Race Course Road and in the station construction by cut & cover method at Clarke Quay station during the construction of the North East Mass Rapid Transit Line in Singapore.
Recent examples include "Stray-Rod," on reports of infidelity on the part of Alex Rodriguez; "Mangenius," a mocking reference to Jets Coach Eric Mangini; and "Marbury One Steph From Gone," on the Knicks' plans to get rid of Stephon Marbury.
As fans pillaged the stadium for mementos, the scoreboard read "N.J. Jets" in reference to the Jets' departure to the Meadowlands.
Senate Majority leader Harry Reid (D-Nevada) recently referenced the Jets' confusion atop the depth chart in trying to describe the post-election struggles to get anything done in DC. "Coach Ryan, he's got a problem.
On Thursday, Mr. Obama made reference to the jet, without singling out Citigroup by name; his remarks came one day after the president met at the White House with business leaders, including Richard D. Parsons, the new chairman of Citigroup.
Several reference locations in the jet are used including points on the jet lip and centerline.
Experiments conducted are (1) without any forced jet stirring (reference case), (2) four jets arranged in a horizontal circle and (3) aligned jets; they were all in a tank containing water with a known homogeneous initial suspended sediment concentration.
Although, the MJSP calculated for all scenarios are higher than those of the fossil jet fuel reference, the significant potential for environmental impacts reduction (in terms of GHG emissions and primary energy use) are encouraging for further research in costs reduction and technology development.
