impinging jet data
Hello everybody out there!

I'm searching for high quality experimental data on impinging heat transfer, preferably with flow measurements as well for CFD validation. Key issues are inlet boundary conditions and geometry: The jet should be confined (by a wall) and channel height(H) through jet width (D) should be about 2 to 8. Axisymmetric jets as well as slot jets will do. Jet Re nr should be between 10000 and 30000. My experience is that jet exit conditions seriously affects calculated heat transfer (especially the turb. lenght scale). Therefore I'm looking for fully developed flow conditions in the jet exit.



ps. If you need a few hints on other exp. setups maybe I can help, I have lots of stuff.

Hi Andreas,

Take a look on the experiments made by Cooper et al. They can be found throug the Ercoftac database, URL:

This case has also served as a testcase for CFD, there is a paper about different turbulence models applied in this case. One of the authors is Tim Craft, at UMIST.

Regards Ander

Hello Anders,

thanks for answering. I'd like to point out that I'm looking for a confined jet exp. setup. This is not included in the Ercoftac base yet. But still, it's an excellent site!

Hi Andreas,

Check out the following paper:

"Numerical study of turbulent heat transfer in confined and unconfined impinging jets", by Behnia et al. , Vol. 20, pp 1-9, 1999.
