Dataset description

This data set contains the measured scattering and absorption coefficients of an area expansion with flow. Measured scattering coefficients of an area expansion for six different flow speeds. Measured absorption coefficients of an area expansion for six different flow speeds. The coefficients are obtained for two assumptions, expanded and non-expanded flow downstream of the area expansion. The coefficients have been measured for plane waves (up to a frequency 2300 Hz), with an area expansion ratio of 0.3086. The following six upstream Mach numbers have been used to obtain the scattering matrices, M=0.00, 0.05, 0.10, 0.15, 0.20 and 0.25. The dataset was originally published in DiVA and moved to SND in 2024.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
