“…The device consists of an evaporation chamber and a heat exchange surface with a distillate collector. Several evaporative stages with condensers, which are connected in series, by counterflow through heated and cooled media, are more often used in flash distillers [5][6][7]. This design allows to increase the thermal efficiency of the installation and reduce its metal consumption.…”

The solution of the problems of increasing energy efficiency at the enterprises of the energy industry is largely due to the competent organization of modern methods of water treatment, which are one of the main units in the technological chain in the production of thermal and electrical energy. Improvement of water treatment technology can be considered as one of the directions of implementation of energy-saving measures at energy facilities. An important task is the introduction of energy-efficient methods of water treatment at thermal stations, including the method of desalination of water. There are the methods of water treatment using instant boiling evaporators, which make it possible to obtain desalinated water for steam boilers in this paper. The efficiency of the proposed water treatment system at a thermal station is shown.

“…Reynolds numbers are in the range from 1000 to 10200. In the previous articles of the authors, heat transfer in an in-line and staggered tube bundle was investigated in the range of Reynolds numbers from 3020 to 6040 [10,11]. In these studies [10][11], only the heat transfer of the central cylinder in the tube bundle was investigated.…”

Abstraction. This article analyzed three RANS turbulence models to predict heat transfer in a in-line tube bundle. The numerical simulations were based on the commercial product AnsysFluent. The RNG k-epsilon model with enhanced wall function, SST, SST k-omega models were employed for turbulence modeling. Numerical simulation was carried out in the range of Reynolds numbers from 1000 to 10200. The obtained data on heat transfer were compared with the known empirical equation. The best agreement with experimental data over the entire studied range of the Reynolds number was obtained for the RNG k-epsilon model with enhanced wall function. The average deviation from experimental data was 6.3%.
