| Outline of Final Research Achievements |
The purpose is to establish a dynamic and low invasive evaluation method for the property and state of the flowing liquid without sampling or installing a sensor in the flow path.
The scattered wave power of water in a cylindrical container was analyzed based on the theoretical relationship between the permittivity and the scattered power irradiated on water in a spherical container. We experimentally derived a correction factor for the dielectric properties, which takes into account the polarization of water.
As a result of measurement with the water circulation mechanism using a pump, there is no significant difference between the scattered wave of the stationary liquid and the flowing liquid was obtained in the range where the changing speed (frequency) of the irradiation electromagnetic field was sufficiently faster than the flow velocity of the liquid. It was confirmed that this method can be applied to the liquid circulation system.
