Despite extensive theoretical research, scientific-practical and various engineering works in the field of separation of residual oil in bituminous sands, the problem remains relevant. For this purpose, the article considers the issue of improving the process of separation of oil from bituminous sands under the influence of physical fields. Keywords: Bituminous sands, ferromagnetic based fluids, magnetic and electric fields, oil yield factor.

Diagnostics And Therapy

Magnetic fluids with nanoparticles dispersed in water or oils offer attractive applications in biomedicine and industry. Biocompatible magnetic fluids are used for diagnostics and therapy in medical applications, in pharmacy, and biosensors. Application of ferrofluids is expanding into energy conservation, faster and efficient cooling, and hence better performance in a wide variety of practical applications (in heat exchangers, mainly in micro-cooling systems). For the study of the influence of an external magnetic field on the aggregation processes of magnetic nanoparticles in magnetic fluids, acoustic spectroscopy was used. The jump changes of the magnetic flux density at various temperatures influenced the acoustic attenuation. The measured changes were results of nanoparticle aggregations into new structures.
