The Determination of Dissolved Oxygen Concentration in Stationary Water

Article Preview

Abstract:

In the paper the differential equation of the transfer speed of the oxygen towards water is numerically integrated, software is written and theoretical results are presented. A setup for experimental tests regarding the functioning of fine bubble generators was designed and built in the frame of the Department of Thermotechnics, Engines, Thermic and Refrigeration Plants laboratory. Measurements regarding the increase of the concentration of oxygen dissolved in water were performed. Theoretical and experimental results were compared.
