The use of electrolysis in the creation of waste-free water purification processes

Methods of water pre-treatment before baromembrane installations in order to remove the predominant amount of salts are proposed. The technological scheme of obtaining high-quality permiate in the amount of 90-95% of the initial volume of water during its preliminary stabilization treatment has been developed. The influence of various factors on the quality and yield of permiate has been established.

Optical-digital processor for thermal imaging surveillance systems image processing

Optical-digital processor for thermal imaging surveillance systems image processing

This paper investigates ways to increase the efficiency of coherent optical spectrum analyzers (COSA). The increase in efficiency is achieved through usage of space-time discrete light modulator in the COSA input and through recording of the spatial spectrum with a matrix detector (MD). The matching of the parameters of the modulator, Fourier lens and MD allowed to improve the technical characteristics of COSA. The matching means the choice of parameters of COSA’s components, which allow to obtain improved characteristics of the COSA.

Development and research of heat dissipation means from high power transmission modules for antenna systems of perspective radars.

About 70 to 75% of the energy consumed by the elements of transmit modules (TM) for active phased antenna arrays (APAA) is converted into heat. This heat, if dissipated inefficiently, can cause the element base to overheat, thus reducing the reliability of the radar. The task of ensuring the normal thermal regime of TMs for APAAs is complicated by the large-scale integration of electronic components inside the TMs.

Heat transfer and fluid dynamics in miniature two-phase heat transfer systems

Heat transfer and fluid dynamics in miniature two-phase heat transfer systems

For the first time a comprehensive study of the processes of heat transfer and hydrodynamics during evaporation and condensation in closed miniature two-phase systems was carried out. The regularities of the influence of geometric and regime factors on the thermal resistance and maximum heat fluxes of miniature heat pipes, thermosyphons and pulsating capillary heat pipes are revealed. The physical model of heat exchange processes in the conditions of limited space at application as heat carriers of ordinary liquids and nanofluids is developed and presented.
