Radiation is one of the three fundamental modes of heat transfer, yet it is often ignored in electronics cooling simulations. One of the reasons it is often ignored is that the core physics are not fully understood. Additionally, the impact of radiation on the predicted temperatures is underestimated, especially in natural convection simulations.
The core physics of radiation as it applies to electronics cooling is discussed in this online seminar, including the visible and infrared radiation spectrum, relevant material properties, solar radiation, and internal radiation. CFD specialists explore radiation options available today in engineering simulation applications. Viewers learn best practices for including radiative effects in their simulation work.
