Abstract
The growth of an electrical discharge channel in water has been simulated by a finite‐difference solution of the partial differential equations of motion along with the descriptive equations of the medium. The computation is based upon a set of parameters which describe experimentally controllable conditions. Close agreement is obtained between simulations and experiments by adjusting arbitrary parameters included in the description of the medium. However, the simulation is relatively insensitive to these parameters.
