Abstract :
An optimized square electrical impedance sensor has been designed for circulating fluidized beds. A 2D mathematical model has been established for the sensor. The sensor has a set of calculable standard values, and thus it is self-calibrated. Based on the conformal transformation theory and precise integration method for elliptic function, a fast image reconstruction algorithm using the model has been introduced. And the results validate the feasibility of the algorithm.
