The processes of dissolution and hydrate forming behind the shock wave in the gas-liquid medium with gas mixture bubbles

The processes of dissolution and hydrate forming behind the front of the shock wave, propagating in liquid with bubbles of carbon dioxide and nitrogen mixture, have been experimentally studied under various initial pressures, medium temperatures and surfactant concentrations in water. The theoretical model of this process is presented for the gas-liquid medium with bubbles of multicomponent gas mixture with consideration of accompanying heat effects. Numerical solutions to this problem were found. Close fit of calculation results and experimental data was achieved. Experimental data on profiles of gas content, times of dissolution and hydrate forming were generalized on the basis of the suggested model. (C) 2011 Elsevier Ltd. All rights reserved.
