Résumé

The following results were obtained: 1) pressure drop for the water/particle slurry containing the surfactant in which particles accounted for about 12% of fluid volume, was 25-50% smaller than in case of flowing water; 2) when transporting the water/particle slurry containing the surfactant, it is advisable to reduce velocity and regulate the Reynolds number to approximately 3X1,000; 3) if the particles in the water/particle slurry are replaced by microcapsules that have a thermal energy storage effect due to their latent heat, the heat transported per unit volume of this slurry becomes twice that of plain water, and the required pumping power is reduced to half that of water.
