Embodiment 1
[0039] The specific process of the ECT sensor structure optimization and electromagnetic field analysis method involved in this embodiment includes parameter setting, geometry setting, material setting, grid division, physical field setting, solution, sensor structure optimization and calculation of electromagnetic field distribution. Eight steps:
[0040] (1) Parameter setting: In COMSOL software (finite element analysis software), input the parameter values of each component in the physical map of the ECT sensor sequentially under the global definition directory: the radius of the ECT sensor measurement field 1 is 7.5cm, and the PVC layer 2 The thickness is 0.5cm, the width and opening angle of copper electrode layer 3 are respectively 4cm and The embedding depth of the radial electrode layer 4 is 0, the radius of the air domain 5 is 10 cm, the radius of the shielding layer 6 is 10 cm, and the impurity area 7 is a water-containing area with a radius of 3 cm and 10×2 cm, s...
