Further Experimental Studies of Cross-Hatching
This limiting point agrees well with the values from the distortion-free probes. The larger probes, however, show decreasing values in the constant-displacement regions. It is interesting to note that if the maximum values of A/D are plotted instead of the constant-displacement values, the agreement with the smaller diameter data is good. Included on this figure for comparison is the level of A/D obtained by previous investigations' in incompressible flow. The displacement level obtained in this study is more than double that obtained previously in incompressible flow.
