Processes arising when a high-velocity liquid drop strikes a rigid obstacle
or a liquid layer were investigated using numerical simulation. The flow p
attern being formed features a complicated interaction of compression shock
and expansion waves between each other and with free surfaces, the initiat
ion of a cumulative jet flow, and the formation of cavitation areas. Factor
s governing the interaction process are analyzed. Obtained results are comp
ared with experimental data. (C) 2000 MAIK "Nauka/ Interperiodica".
