Abstract

Abstract

A zero-dimensional model is proposed to analyze the magnetic flux compression process of a thin cylindrical liner driven by electromagnetic force.The magnetic energy conversion efficiency and 3 optimal dimensionless parameters (h, A, Π) in the magnetic flux compression process are obtained by solving the equation set consisting of LC circuit equations and equations of motion of a thin cylindrical shell.It is shown that in order to achieve a 10-fold compression of cylindrical shell under the condition of steady current, the parameter h should be less than 0.2.To obtain a compressed magnetic field up to 1 000 T with high magnetic energy conversionefficiency, the dimensionless parameters are optimized on the condition that the capacitor bank's energy is about 1 MJ.These analyses and simulations are of great importance for both theoretical and experimental studies on magnetic flux compression.
