Busbar with Surface-to-Surface Radiation

This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.3 (heavily oxidized). A more ... Saiba Mais
