CONJUGATE HEAT TRANSFER U-SHAPED SILICON ROD WITH THE ENVIRONMENT WITH GAS THERMOGRAVITATIONAL CONVECTION

The conjugated natural convective heat transfer of electrically heated U-shaped silicon rod which placed in a rectangular container filled with gas with isothermal cold walls was numerically studied in a three-dimensional formulation of the problem. The temperature was maintained constant at the control point which placed on a surface of the U-shaped rod by selection of voltage. Temperature difference between the control point and the cold walls is 70 K. The equations of natural convections in Cartesian coordinates with Boussinesq approximation in terms of temperature, vortex and vector potential of velocity field were solver by FEM. Convective flows spatial form and temperature fields inside gas and the solid were investigated.
