NASA Langley flow-impedance tube benchmark data

[Sen Peng]

Hi,everybody,
I am working on a duct acoustics problem. I wrote a Finite Element
program solving the acoustic field in the NASA Langley flow-impedance
tube. Now I am searching for the benchmark data to validate my
computed results, which may be find in the following reference:
Tony L. Parrott, Willie R. Watson, and Michael G. Jones, "Experimental
validation of a two-dimensional shearflow model for determining
acoustic impedance," NASA TP-2679, May 1987.
If someone can get such a paper, would you mind sending me a copy? My
email address is ***@gmail.com, I will be very grateful for
your help.

Sincerely,
Sen Peng

Hi Gordon,
I am searching for such a paper too. I get the message when I click on the link that you suggest:
"The NASA technical reports server will be unavailable for public access
while the agency conducts a review of the site's content to ensure that it
does not contain technical information that is subject to U.S. export control laws and regulations and that the appropriate reviews were performed.
The site will return to service when the review is complete.
We apologize for any inconvenience this may cause."

Maybe you could send me a copy in pdf?

Thanks,
Pablo

Hi Peng,
I am a researcher from Brazil and I am searching for such a paper too. I get the message when I click on the link that Gordon suggested:
