Approximate kinetic solutions are found for Coulomb explosions of nanostructures in plane (thin foils), cylindrical (nanowires/tubes) and spherical (nanospheres/shells) geometries. The distribution function, mean velocity, density distribution, as well as the energy spectra for accelerated ions are derived. The proposed kinetic model describes physics of multiple flows that occur during Coulomb explosion. Comparison with particle-in-cell numerical simulations shows good agreement with analytical results.
