| Abstract: | A boundary intergal formulation is proposed to analyse the temperature field of injection mold.Networks of cooling channels within the mold and the closely spaced mold cavity surfaces require special attention both in the formulation and numerical treatment of the integral equations. The proposed formulation couples the boundary formual, the gradient of the boundary formula and the exterior formula.The derivation of the integral equations is presented here along with an efficient numerical method for intergation of some of the kernels in these equations and a semi-analytical procedure for the integration of the highly singuar integrands.An example is demonstrated to illustrate the usefulness of the numerical method developed. |
