Development of a simple model for predicting the spark-induced bubble behavior under different ambient pressures

摘要: In this paper, a simple model was developed to predict the dynamics of spark-induced bubble under different ambient pressures. This work helps in developing deep-towed plasma sparker, as can bubbles subjected very high pressures (about 20 MPa) which normally are difficult obtain experimentally. Experimental results indicate that maximum radius for fixed discharge energy decreases power-law function pressure up 1.0 MPa; period also quickly with increasing pressure. For constant value ratio energy, modeling both and good agreement experimental results. Both sets is proportional
