In this paper, the acoustic impedance of a liner is educed by a novel semi-analytical inverse technique. The liner sample is placed flush with the solid walls in a rectangular duct with grazing flow. The technique uses complex acoustic pressure measured at four positions at the wall of the duct, upstream and downstream of the lined section, and educes the impedance with a mode-matching method. Previous studies neglected grazing flow nonuniformity and the pressure discontinuity that appears at the liner-wall boundary caused by the discontinuity of the acoustic particle velocity into the wall. In the present paper, the mode-matching formulation is rederived in terms of pressure instead of velocity potential which is found to be more numerically stable.

It has a cafeteria sells coffee, soda, crispy critters tartlets, sandwiches, teas and other things. When I went we ask cappiccinos and chicken pot pie and a the chessecake little chicken is very well served and the cappuccino too, so much that the chessecake had to share. All very yummy. There only accepts debit card in the cafeteria, but the store accepts credit.

Has a gift shop with many interesting products, Brasilia well made and alternative things. There's a café serving simple basics. Is a meeting place, and more informal meetings. Tip: carrot cake with chocolate is amazing! Shop prices are not so cheap, but who wants to buy a really nice souvenir of Brasilia is a tip.
