# Design of a New Supersonic Shock Wave Generator and Application in Power Generation
## 4 Design of a Power Generation System Driven by Supersonic Shock Waves  
### System Design  
We designed and developed a power generation system based on the new shock wave generator [32]. Figure 11 shows the architecture of the power generation system driven by supersonic shock waves. The functions of the components in the system architecture in Figure 11 are described as below:  
1. Shock wave generator: This comprises a high-pressure storage tank and a balanced valve stem. When the balanced valve stem moves backward and the gases in the high-pressure storage tank reach the set pressure, the generator can generate shock waves that rush out of the homogeneous jet nozzle. 2. Valve stem controller: This can drive the balanced valve stem of the shock wave generator forward and backward. When the balanced valve stem moves backward (ON), the generator generates a shock wave, and high-pressure gas rushes out to drive the Tesla turbine to rotate. When the balanced valve stem moves forward (OFF), the output of high-pressure gases stops. 3. Gas source: this is a high-pressure gas cylinder or an air compressor that provides high-pressure gases for the high-pressure storage tank of the shock wave generator. 4. Regulator: this can adjust the gas pressure output from the gas source. 5. Flow detector: this detects the gas flow \(f_{g}\) delivered from the gas source to the high-pressure gas storage tank. The flow signals detected can be transmitted to the monitoring host through the signal transformation unit. 6. Tank pressure detector: This can detect the gas pressure \(p_{t}\) in the high-pressure storage tank of the shock wave generator. The pressure signals detected can be transmitted to the monitoring host through the signal transformation unit. 7. Output pressure detector: This can detect the gas pressure \(p_{o}\) output from the shock wave generator. The pressure signals detected are transmitted to the monitoring host through the signal transformation unit. 8. Tesla turbine: The turbine can rotate through the impact of shock waves and high-pressure gas and can continue to rotate after the high-pressure gas stops through its energy storage inertia. The rotated turbine can rotate the rotating rod and then drive the magnetic energy generator to work. Figure 11: The architecture of the power generation system. * Rotation speed detector: This can detect the rotation speed \(s_{r}\) of the rotation rod. The speed signals detected are transmitted to the monitoring host through the signal transformation unit. * Magnetic energy generator: This comprises a rotating permanent magnet and a stationary coil. The rotating rod rotates to rotate the magnet to cut magnetic lines and generate power. According to the principle that magnet motors can rotate sustainably due to magnetic action, it can supplement the heat consumed by friction, increase the continuous high-speed magnet rotation time, and improve the power generation efficiency. * Power control unit: this can convert the alternating current generated by the magnetic energy generator into direct current and provide it to the power output unit. * Voltage detector: This can detect the voltage \(V_{p}\) of power generated by the magnetic energy generator. The voltage signals detected are transmitted to the monitoring host through the signal transformation unit. * Current detector: This can detect the current \(I_{p}\) of power generated by the magnetic energy generator. The current signals detected are transmitted to the monitoring host through the signal transformation unit. * Power output unit: This contains an energy storage battery and a load unit. The load unit is a light bulb box containing three parallel light bulbs. Users can turn each light bulb on or off. The power provided by the power control unit can charge the energy storage battery or directly supply the power required by the load unit. * Signal transformation unit: This is an Advantech USB-4711A multi-functional high-speed signal acquisition and control card [33].
