Simulation and experimental studies have been used in this paper regarding the importance of the plasma pulse system (PPS) to create a uniform discharge plasma channel and a strong shock wave. First, the effect of wire geometry on uniform plasma production is simulated. The simulation results show that a wire with a diameter of 0.4 mm and a length of 50 mm is an ideal geometry for the plasma pulse system because it produces a more uniform plasma. Second, the shock wave generation mechanism was investigated experimentally in the explosion process of two wires with thicknesses of 0.2 and 0.4. As the diameter of the wire increases and its resistance decreases, the discharge current peak increases, and the tendency to establish periodic currents increases, so the 0.4 wire gives better experimental results in terms of shock wave power than the simulation results that confirms the smaller the diameter of the wire, the current generated in a pulsed manner in a short period, and sufficient energy is not stored to change the state of the wire and, as a result, to create a strong shock wave in the wire. Finally, it simulated underwater using COMSOL Multiphysics. It shows that the pressure drops immediately after the explosion point. Based on this, a pressure of 20 MPa has been obtained at a distance of 10 cm from the explosion point, and this reduction rate continues exponentially.
