Departmental theme

1.7.1.810 “Research of heat and mass transfer processes of liquid fuels components producing to create innovative technologies for fuel emulsion production”

The nature of the DPIE influence on the structural and mechanical properties of heterogeneous dispersed systems was researched. The methods for producing stable emulsions from non-polar and weak polar liquids using DPIE effect were studied. The liquid fuels with biocomponents, such as oil and ethanol, with the content of ethanol in the mixture of 30% by weight were chosen as model medium examples.

The theoretical research of the three-dimensional structure of the flow (velocity fields, pressures, energy and temperature dissipation) in the proposed model of rotary-pulsation apparatus (disc-cylinder type) was carried out. The rotary-pulsation apparatus realizes complex of physical DPIE effects. The research results allowed to see the complete hydrodynamic picture of the fluid movement, and on the basis of these parameters of hydrodynamic and thermal flow disturbances to generalize the possible dispersion mechanisms of heterogeneous systems.

1.7.1.844 “Research of hydrodynamic and heat and mass transfer processes in micro- and nano-structured disperse media”

The cooling properties of meso- and nanofluids on the basis of vegetable oils produced by DPIE method were investigated for the first time. The different thermo-physical properties of the fluids depend not only on the composition of vegetable oils, but also on the nature, size and dispersed particles and production methods of cooling media.

DPIE processing method allowed to increase the cooling capacity of vegetable oils in 1,1 … 2,9 times at the high temperature range (600-850 ° C).

The qualitative difference of cooling fluids based on rapeseed and soybean oils was the lack of film boiling stage, which led to increase heat removal rate and uniformity of cooling of the sample at high temperature range (600-850 ° C).

The character of a contact interaction between the structural elements of the particles and between the nanostructures and the dispersion medium was taken into account in the research. The cooling rate in xerogel methylsilicic acid fluid with a predominance of phase nanostructure contacts significantly exceeded the intensity of cooling in the silica fluid with coagulation contacts between nanoparticles.

1.7.1.852 “Development of methods for intensification of hydration, hydrolysis and extraction based on using of Discrete-Pulse Input of Energy mechanisms”

The thermal diffusion method of extracting active ingredients is designed for intensification of the extraction process. The essence of the thermal diffusion method of extraction is alternating filtering through extracting the raw material layer. Flow rate of extractant is selected such as to provide a laminar flow regime in the extractant layer material. The extracting temperature is changed in the oscillating mode. The extractant alternating filtering allows to speed up the external mass transfer, and oscillating temperature extracting mode allows to speed up internal mass transfer. The effects of these parameters significantly intensify the extraction process.

The intensification of the extraction process has been implemented in the plant “Riga-1000” for the production of herbal medicines which was developed for Riga pharmaceutical factory. Furthermore, the method was used in the pilot thermal diffusion plant for BAS extraction with liquefied gases in Zhitomir Enterprise “Liktravy”.

1.7.1.860 “Theoretical and experimental researches of heat and mass transfer in technological processes using the Discrete-Pulse Input of Energy method. ”

The improvement of suppository medicinal forms (MF) production using thermocontact melting and Discrete-Pulse Input of Energy method was proposed for melting, mixing, dispersing and homogenizing during the preparation of suppository medicinal forms (MF).

The use of DPIE method allowed obtaining the stable mixture of hydrophilic and hydrophobic components, improving the quality of suppository medicinal forms (MF). Furthermore, the thermocontact local melting method based on the direct contact with the heating substance was used to prevent overheating.

The technology and the plant “Termobat-M” for melting structures for the production of soft medicinal forms was developed. The documents for validation of equipment in accordance with GMP requirements were prepared.

1.7.1.840 “Research of microscale thermal processes in complex heterogeneous systems effected by Discrete-Pulse Input of Energy mechanism to develop new technologies and products”

The new heat currier based on the geo-mineral aqueous concentrate with predominance of sodium salt and magnesium chloride with low corrosive influence to the metals was obtained by the DPIE method. The corrosive influence to the metals was 2-6 times lower than that of water; the temperature of crystallization was to -30 ° C, and boiling point was up to + 106 ° C.

The designed and manufactured disc-cylinder apparatus provides the DPIE method. The apparatus is used to obtain high dispersed liquid systems, which include the meso- and nanofluids. The experimental studies have shown that the cumulative influence of hydrodynamic, hydroacoustic and hydromechanical properties in heterogeneous environments was a promising method to produce superfine systems. The pressure pulsation oscillograms for different flow regimes of model environment in the disc-cylinder apparatus were received in the modernized stand for the research of hydrodynamic and hydroacoustic effects by DPIE method in heterogeneous environments.

The structure formation in “silicon dioxide – distilled water» nanofluids was researched with the help of numerical simulation and the obtained results were compared with the experimental sample of nanofluid prepared by DPIE method in the rotary-pulsating disc-cylindrical apparatus.
