4. Conclusion Experiments on loading surfactant solutions and distilled water under the conditions of an electric explosion of a wire have been carried out. Velocity profiles of free surfaces of liquids are obtained and their relaxation properties are estimated. The shear viscosity of Survogel, in contrast to water and Guar, changed insignificantly in the studied range of deformation rates. Analysis of the velocity profiles of the free surface of liquids showed a significant attenuation of the shock wave in surfactant solutions, in contrast to water.
