Mechanism of the Shock Wave Generation and Energy Efficiency by Underwater Discharge

Pressure Shockwaves to Enhance Oil Extraction fromJatropha CurcasL.

“…Based on work by Higa et al (9), the hypothesis considered was that the pressure shockwaves may also enhance the yields of extracted oil. Other papers (2,5,10,11,14,16,21) reinforced this assumption.…”

Experimental Study and Computational Simulation for Shock Characteristics Estimation of Okinawa’s Soils “Jahgaru”

“…Jahgaru, the optical observation using the shadowgraph system [4][5][6][7][8][9] have been performed to evaluate the shock wave induced by the detonation. The large number of studies using shadowgraph method for shock wave visualization has been reported in the past.…”

Optical Examination of Shockwave Propagation Induced by an Underwater Wire Explosion

“…Figure 1 is a rice powder-manufacturing system [11][12][13]. The rice powder-manufacturing system mills rice by applying a shockwave to the rice that circulates in a silicone tube placed in the pressure vessel.…”

“…When pulse power is applied to the wire, the electrical energy rapidly sublimates the wire, thus ___________________________________ *Corresponding Author: osamu@okinawa-ct.ac.jp converting it into plasma along with the surrounding water. At this instant, an underwater shockwave is generated around the rapidly expanding plasma [11] [14][15][16]. A high-voltage pulse generator is used for supplying high-voltage, large-current electrical discharge to the wire (Figure 2A).…”
