Simulation of Electrohydrodynamic Phenomenon using Computational Intelligence Methods

Abstract The electrohydrodynamic effect occurring during an underwater electrical explosion of a copper wire and method of its simulation using computational intelligence algorithms are presented in the paper. Principles of operation of the seismic wave EHD generator are explained. Differential equations describing a mathematical model of changes in a release circuit of the EHD generator are provided. The results of computations of differential equations, using Runge -Kutta algorithm, are provided. The simulation is based on current intensity and pressure data sets recorded during field experiments and data obtained by solving differential equations of the theoretical model. The relationships between electrical parameters of the electrohydrodynamic discharge circuit, material parameters of the exploded wire and result- ing pressure values of the shock wave are discussed. A regression model is created using computational intelligence algorithms for prediction of pressure values of a seismic wave resulting from the explosion of the wire. The results of the prediction of the pressure wave using neural networks are presented in the paper and verified by comparing the measured and calculated values of the pressure wave.
