title = "Determination of the Discharge Coefficient in Improved Empirical Impedance Model of Plasma Channel for Underwater Spark Discharge",
abstract = "The empirical time-varying resistance model of the plasma channel Rpl(t) = β l2/Win(t) in underwater discharge has been widely used, but the internal energy of the plasma channel Win(t) is difficult to obtain and the discharge coefficient β varies widely under different experimental conditions. This article introduces an improved empirical plasma channel resistance model Rpl(t) = β l2/Epl(t) as well as a method for determining the discharge coefficient β. The effectiveness and the feasibility of the method are verified by comparing the simulation results and test results. The improved plasma channel resistance model and the method to determine the discharge coefficient can help guide the application of electrohydraulic shockwaves.",
