THE DUAL-RECIPROCITY METHOD FOR HEAT-TRANSFER IN POLYMER PROCESSING

This paper presents a boundary-element simulation of the heat transfer during polymer processing. The governing equations, boundary integral s and fundamental solutions, with their numerical implementation for h eat transfer and creeping flows, are presented. Viscous dissipation an d internal-heat generation for curing polymers is included in the equa tions. In order to calculate the transient-heat transfer and internal- heat generation, the dual-reciprocity boundary-element method is appli ed. The heat-transfer-simulation results are in good agreement with an alytical and other numerical results.
