电弧等离子体在超临界CO2中产生的冲击波具有产生新型反应场的潜力。然而,在SC-CO2中的冲击波特性的研究很少。研究了纳秒脉冲电弧等离子体产生的冲击波在SC-CO2中传播的可视化结果。利用时间分辨阴影成像技术,对放电通道中传播的圆柱形激波进行了观测。脉冲电弧等离子体在圆柱形暗区产生的激波在64纳秒内分离。研究了从高压气相到SC相的CO2介质密度对激波马赫数的影响。马赫数在临界CO2密度水平处达到局部最大值.马赫数的异常可以用在接近SC-CO2临界条件下CO2比热容比的局部极大值来解释。
Shock waves generated by arc plasma in supercritical (SC) CO 2 have the potential to create novel reaction fields. However, there have been few studies of shock-wave characteristics in SC-CO 2. This study provides the results of visualization of shock-wave propagation in SC-CO 2 generated by nanosecond-pulsed arc plasma. A propagating cylindrical shock wave originating from a discharge channel was observed using time-resolved shadowgraph imaging. The shock wave separated from the cylindrical dark-region induced by pulsed arc plasma within 64 nanoseconds. The Mach numbers of the shock waves were investigated against the medium density of the CO 2 ranging from a high-pressure gas phase to the SC phase. The Mach number reached a local maximum at the critical CO 2 density level. The anomaly in the Mach number can be explained by the local maximum of the specific heat capacity ratio of the CO 2 at close to the critical condition of SC-CO 2.
