Calculation of the parameters of a surface water aerator based on the use of solar energy

Currently, technical solutions based on the use of renewable energy sources, mainly solar and wind, are being widely developed. The main directions of using solar radiation proper are technologies for obtaining thermal energy in water heating installations and (or) electric energy using photovoltaic converters combined into photovoltaic modules. In the wind energy industry, the kinetic energy of air masses in the atmosphere is converted into electrical, mechanical, thermal and other forms of energy. Modern principles of creating aeration systems for natural reservoirs using renewable energy sources are based mainly on traditional energy conversion technologies. For example, solar energy is converted into electrical energy using photovoltaic converters, and kinetic wind energy is converted into mechanical energy, followed by air injection into the distribution network of aerators. The purpose ofthis work is to theoretically substantiate the volume of the storage tank from the conditions for the formation of an optimal oxygen concentration in a reservoir. The article presents the results of theoretical studies that made it possible, based on the equation of state applied to the thermodynamic storage tank system, as well as taking into account the hydrodynamic operating conditions of the device, to obtain a dependence for determining the volume of the storage tank design necessary to eliminate oxygen deficiency in the reservoir water.
