ALGORITHM ENHANCEMENT FOR COUPLING HEAT CONDUCTION AND NATURAL CONVECTION

摘要：

Conjugate heat transfer occurs in many fields, including building ventilation, thermal insulation, electronic coolings, etc. Three main methods, vacant proportion practice (VPP), large source practice (LSP) and viscosity coefficient practice (VCP), are used to deal with the coupling of solid-fluid phases, i.e. the conjugate heat transfer. These methods are inefficient for real numerical simulations. The new one, taking into account that the iteration essence of SIMPLE method and directly involving the effects of solid phase into pressure-correction equation is presented in this work. A benchmark example, a square cavity centered with an obstacle, is presented. The results demonstrate that the new method of coupling solid-fluid region is more efficient than others in terms of computational accuracy and efficiency.
