Criterion Prediction of Changes of Shock-Wave Structure at Transonic Flow Around Airfoils with Local Impulse Energy

The results of numerical modeling of transonic streamline of profile with a local pulse energy supply were generalized in terms of criteria analysis for a wide range of parameters. Defined set of criteria allows predicting not only the degree, but the features of the flow transformation. A comparison of the results of the criteria analysis with numerical calculations of transonic streamline (Mach number M∞ = 0,85) of a symmetrical profile NASA-0012 were performed for energy supply in areas such as narrow and compact form
