Essay

The novel highly-efficient energy and resource saving technologies for production of disperse solid, liquid and paste materials were theoretically and experimentally grounded. This solution is based on results of fundamental investigations of heat- and mass transfer and hydrodynamics in curved channels of vortex acoustic chambers. Novel energy and resource saving technique to produce disperse materials were developed using enhanced processes due to combined action of centrifugal forces, vortex flow turbulization and acoustic self-excited oscillations of different frequencies under mechanical tensions with the rational energy transformation. On this basis a few vortex energy and resource saving technologies, compact plants and devices with enhanced heat- and mass transfer and highly-effective processes of dispersion, separation, drying, fractionation and mixing processes were designed. The scientific and design foundation to design vortex acoustic chambers with aerodynamically profiled elements and resonators generating intensive fluctuations of acoustic, vortex and pulsating disturbances of the vortex flow parameters were developed. The basic mechanism of heat- and mass transfer and reciprocal action was disclosed; interrelation between external conditions and internal processes determining flow regime parameters with extraction of limiting conditions was determined.Theoretical and actual models have been proposed enabling to obtain correlations describing basic dispersion parameters of dispersion in vortex flow. The method of a process intensification by means of combined action of centrifugal forces, vortex flow turbulization and acoustic self-excited oscillations with matched dispersion processes was proposed. The high enhancement of heat- and mass transfer in curved channels of vortex chambers was established enabling to develop the calculation procedures for heat-utilizing devices and compact vortex plants. High-effective vortex energy and resource saving technologies and plants producing the finelydispersed systems have been developed and introduced into the practice. The novelty of these devices is so, that they have been protected by 42 intellectual property certificates and patents of the Ukraine.
