DETERMINATION OF THE REQUIRED POWER OF TUBE ELECTRIC HEATER FOR DISTILLATION DESALINATION PLANT

Tube electric heater is required for distillation process because it prepares input water for working process on the start regime of the desalination plant Depending on its power, time consumed for start regime will vary. Correspondingly, selection of the power for tube electric heater depends on amount of water inside, mass-dimensional characteristics of the desalination plant and heat transfer with the environment Algorithm for power selection is developed

DETERMINATION OF THE CRITERIA FOR COMPARATIVE ANALYSIS OF DESALINATION PLANT

Comparative analysis of distillation desalination plant requires certain criteria. This criterion must take into account both energy consumption and seawater salinity. Relation of the minimal work required for seawater desalination to energy consumption was selected as such criterion

Numerical Modelling of Evaporation Process in Cryogenic Systems

This article deals with a problem of evaporation numerical modeling in cryogenic systems of constant volume. Particularly, a method of nitrogen evaporation modeling in cryogenic fueling tank was considered. User-defined functions of nitrogen thermodynamic properties in temperature range of 70…400 K and pressure range of 0.1…30 MPa. The result of this research is calculation algorithm which allows to model processes of phase change in cryogenic systems with constant volume. A comparison obtained between results of numerical modeling with experimental and analytical data is presented. Deviation of results from experimental data is 5-10%
