Abstract

Presents a two-dimensional convection-diffusion analysis under the condition of high Peclet number by the boundary element method. The newly developed Green´s function which includes speed electromotive force and eddy currents is proposed for the formulation. In order to analyze the large Peclet number problem, attention is paid to the property of the Green´s function; hence, the accuracy is improved. In order to examine the validity of the present method, it was applied to a magnetic sensor for nondestructive testing
