Star wire arrays were used to control the imploding plasma flows and study plasma interpenetration. These arrays consisted of linear "rays" aligned azimuthally and extending from the vertical axis. Star arrays with two close located wires ("gates") instead of a single wire on the inner cylinder were studied for transparent and nontransparent regimes of propagation of imploding plasma through the gates. Nontransparent mode of collision is typical for regular star wire arrays and it was also observed in Al stars with gate wires of regular length and with the gate width of 0.3-2 mm. The cascade process of implosion in stars and trapping of imploding plasma in 1-2 mm gates were modeled with the three-dimensional resistive magnetohydrodynamics code. The intermediate semitransparent mode of collision was observed in Al stars with long Al "gate" wires. A transparent mode was observed in Al stars with long stainless steel or W gate wires. Applications of wire arrays with controlled plasma flows are discussed.
