Application of Electrical Impedance Measurements’ Method for Studies of Bubble Flows

Konovalov, I. A.; Chesnokov, A. A.; Barinov, A. A.; Dmitriev, S. M.; Khrobostov, A. E.; Makarov, M. A. (БНТУ, 2021)

One of the important tasks in carrying out a computational justification of the reliability and safety of equipment that is part of the projected nuclear power plants today is the modeling of the bubbly regime of the coolant flow. In this regard the aim of this work is the use of extended methods of using matrix conductometric systems which are widespread in research practice for ...

Development and Testing of a Methodology for Assessing of the Correlation Velocity Measurements’ Accuracy for the Hydrodynamic Investigations of the Turbulent Coolant Flow in Nuclear Reactor Elements

Konovalov, I. A.; Chesnokov, A. A.; Barinov, A. A.; Dmitriev, S. M.; Khrobostov, A. E.; Legchanov, M. A.; Borodin, S. S.; Makarov, M. A. (БНТУ, 2021)

The correlation method of the coolant flow measuring is widely used in research practice including for studying of turbulent coolant flows in scale models of elements of nuclear power plants. The aim of this work was to develop a technique for assessing the effect of noise recorded by a measuring system on the flow rate readings obtained using the correlation method. A technique ...
