| Abstract: | Analyzing the integral singularity in 3 D boundary element method for cooling simulation, a scheme is adopted to eliminate the second singularity for two types of units by using different linear interpolation function individually and degenerated integral transformation. The expression of integral computation is given for the special unit with source point. |
