One of our recent models included a “hot” process fluid pipe in proximity to an I-Beam that was used to support a pipe rack. We had to estimate the I-Beam temperature due to radiative heat exchange between the I-Beam/ “cold” pipe rack and the “hot” process fluid pipe. In addition, natural convection was also applied over the I-Beam/ pipe rack.
This heat transfer analysis was done using ANSYS.
Surface-to-surface radiation exchange played a major part in the eventual structural design of the I-Beam & supports.
