JSM EXPERIMENTAL DATA: Oil Flow Images

3rd AIAA CFD High Lift Prediction Workshop


 
 
 

Many oil flow images are available from the JSM experiment. The conditions are Re=1.93 million per mean aerodynamic chord, M=0.172.

NOTE: JAXA naming convention "Case 1" in the following refers to the JSM with Nacelle/Pylon OFF. This corresponds to Workshop Test Cases 2a and 2b.

NOTE: JAXA naming convention "Case 2" in the following refers to the JSM with Nacelle/Pylon ON. This corresponds to Workshop Test Cases 2c and 2d.
 

Nacelle/Pylon OFF:

AoA=4.36 deg:

example oil flow image for nacelle/pylon off, alpha=4.36 deg

AoA=10.47 deg:

example oil flow image for nacelle/pylon off, alpha=10.47 deg

AoA=18.58 deg:

example oil flow image for nacelle/pylon off, alpha=18.58 deg

AoA=21.57 deg:

example oil flow image for nacelle/pylon off, alpha=21.57 deg

Download all the Nacelle/Pylon OFF photos (contains Powerpoint files and PDF files in a tarred gzipped directory): Case1-Surface_Flow.tar.gz (123 MB).

Note: the oil flow for the nacelle-pylon OFF conditions were taken with peniche of 30 mm height (all other data for this workshop used 60 mm peniche height). However, the differences in aerodynamic forces between the 30 mm and 60 mm peniche was small, and there is confidence that the oil flows are still representative.


 

Nacelle/Pylon ON:

AoA=4.36 deg:

example oil flow image for nacelle/pylon on, alpha=4.36 deg

AoA=10.48 deg:

example oil flow image for nacelle/pylon on, alpha=10.48 deg

AoA=18.59 deg:

example oil flow image for nacelle/pylon on, alpha=18.59 deg

AoA=21.57 deg:

example oil flow image for nacelle/pylon on, alpha=21.57 deg

Download all the Nacelle/Pylon ON photos (contains Powerpoint files and PDF files in a tarred gzipped directory): Case2-Surface_Flow.tar.gz (31 MB).
