Comparison With Experimental Data

Numerical investigations and comparison with experimental data of the shock wave interaction with aqueous foam barrier are conducted, taking into account the change of the foamy veil density on time. The efficiency of damping properties of foam barriers depends on water content is evaluated.

Shock Unsteadiness

An explicit cell-centered finite volume solver coupled to a k−ε turbulence model corrected for structural compressibility fails to satisfactorily predict the behavior of under-expanded supersonic jets exhausting into still air, because the model does not properly account for the turbulence/shock wave interaction. Two approaches are examined: imposing a realizability constraint and taking into account shock unsteadiness effects. Although both corrections yield better agreement with experimental data of under-expanded jets, the realizability constraint yields better results than the shock unsteadiness correction.
