What are differences between Surface to Surface and Discrete Ordinates models in Ansys Fluent?

 The Surface-to-Surface (S2S) and Discrete Ordinates (DO) models in Ansys Fluent are both used for simulating radiative heat transfer, but they have different approaches and applications:



Surface-to-Surface (S2S) Model

Discrete Ordinates (DO) Model

In summary, the S2S model is ideal for scenarios where the medium does not interact with radiation, focusing on surface interactions, while the DO model is more versatile, handling interactions within the medium and complex geometries.

Case Stduies for each model

Surface-to-Surface (S2S) Model Case Studies
