Three Dimensional Imaging of a Mass Flow |
摘要 |
A method for determining the electrical conductivity of a mass flow in a three dimensional target volume including the steps of placing electrodes in a measuring connection with the target volume; supplying alternating voltage or alternating current to the tar-get volume between two of the electrodes and measuring the current or the voltage between the electrodes; determining a state space model which defines the relationships between the electrical conductivity, the voltage and the current in the target volume and the evolution of the electrical conductivity as a function of time; comparing the currents and/or the voltages according to the state space model with the supplied and the measured ones; and modifying the state space model to decrease any differences. The electrodes are placed substantially within one plane; and the state space model is determined so as to the time-dependent flow field of the mass flow within the target volume. |
