Data Needed for Impinging Jet Research

Click For Summary

Discussion Overview

The discussion centers around the search for reliable data on radial and axial velocities of an impinging jet on a perpendicular plate, specifically for Reynolds numbers between 10,000 and 60,000. Participants are looking for published research to compare with their own experimental measurements using Laser Doppler Anemometry (LDA).

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests reliable data for their upcoming experiment on impinging jets, seeking journal articles for comparison.
  • Another participant suggests several reputable journals where studies on underexpanded and subsonic impinging jets can be found, indicating a wealth of research in this area.
  • A third participant provides specific cases from the ERCOFTAC database, mentioning Reynolds numbers of 23,000 and 70,000, and links to additional complex cases.
  • A fourth participant references a specific article titled "Turbulent flow in the near field of a round impinging jet" published in the International Journal of Heat and Mass Transfer, suggesting it may meet the requestor's needs.

Areas of Agreement / Disagreement

Participants generally agree on the availability of research and resources related to impinging jets, but there is no consensus on a single source of data that meets the specific criteria requested.

Contextual Notes

Participants have not specified the exact parameters or conditions of the data they seek, and there may be limitations based on the definitions of the Reynolds numbers or the specific configurations of the impinging jets discussed.

llo,

I am looking for some good reliable data of radial and axial velocities of an impinging jet on a perpendicular plate for Reynolds number of between 10,000 and 60,000. I am about to conduct my own experiment using an LDA to measure velocities but am looking for some good data to compare both sets of velocity measurements to.

If anyone has any good journals or articles they can suggest it would be appreciated.

Thanks

MM
