An over-utilized condition should be applied in determining the gradient equation, this differs from our previous relevant studies. Numerical experiments by using different measurement errors, measurement positions and number of sensor were performed to justify the validity of the conjugate gradient method in solving this shape identification problem. Finally it is concluded that the present algorithm can estimate the accurate interfacial configurations.
