Conjugate Heat Transfer
The simulation of heat transfer from both solid and fluid within a single simulation can improve accuracy of the results as well as turnaround time. STAR-CCM+’s meshing tools are a key enabler of accurate CHT analysis allowing both fluid and solid to be automatically meshed conformally, removing the need for mapping routines or interface interpolation.
Where the solid structure of interest is thin, STAR-CCM+ has the option to replace the solids with a zero-thickness shell. These solid shells allow for the study of in-plane conduction within the structure without having to mesh the full thickness. This saves time both in the meshing and the solution phases of the simulation.
STAR-CCM+ has a comprehensive set of tools for the modeling of radiative heat transfer from simple surface to surface transfer through to discrete ordinate modeling (DOM) for participating media.
STAR-CCM+’s surface to surface radiation modeling capabilities cover a wide range of different applications with models for both gray thermal and multi-band radiation. For the simulation of solar radiation, STAR-CCM+ has a dedicated model including a solar loads calculator which automatically calculates solar sources based upon geographical location and time/date. When interacting with solids and boundaries, the radiation model can handle both transparent and partially transparent objects as well as specular reflectivity.
