Shock waves in non-Newtonian bubbly liquids

Propagation of non-stationary shock waves in a bubbly liquid with a non-New tonian carrier phase was investigated numerically. The research is carried out within the one-velocity two-temperature two-pressure model of multiphas e media mechanics. An aqueous solution of polymer was used as a non-Newtoni an carrier phase. It was concluded that the behavior of shock waves in Newt onian and non-Newtonian bubbly liquids with the same Newtonian viscosity ma y have fundamental differences. The influence of defining parameters of the two-phase mixture and wave on the structure of shock waves was examined. T he numerical analysis of evolution and attenuation of pulse perturbations w as carried out. (C) 2001 Elsevier Science Ltd. All rights reserved.
