Description
S2S Radiation Heat Transfer Description
The present simulation is about S2S radiation heat transfer via ANSYS Fluent. In this project, plates model the three boxes, and inside these boxes, a tube is designed. The fluid flow inside the tube moves at a temperature of 283 K and a velocity of 20 m/s, and there is airflow inside the boxes around the tube.
It is assumed that these metal plates have a heat source of 1133333.33 W/m3. It is also assumed that radiation heat transfer occurs between the box plates and the surface of the tube. Therefore, the software has used the surface-to-surface (S2S) radiation model.
The surface-to-surface radiation model calculates the radiation exchange in an enclosure of gray-diffuse surfaces. The exchange between the two surfaces depends partly on their size, separation distance, and orientation. These parameters are calculated by a geometric function called a “view factor”. The main assumption of the S2S model is that any absorption, emission, or scattering of radiation can be ignored; Hence, only surface-to-surface radiation is considered for analysis.
The S2S model assumes that the pages should be gray and diffuse. The emissivity and absorptivity of a gray surface are independent of the wavelength, and according to Kirchhoff’s law, the emissivity is equal to the absorptivity (ε = α). Also, the reflectivity is independent of the outgoing (or incoming) directions for a diffuse surface.
Geometry & Mesh
The present geometry is designed in a 3D model via Design Modeler The computational zone is related to the interior of three boxes created by several plates. An output boundary is considered between each of the boxes. A pipe is also passed through the interior of these boxes.
The mesh of the present model has been done via ANSYS Meshing. Mesh is structured, and the number of production cells is equal to 2101788.
Set-up & Solution
Assumptions used in this simulation:
- Pressure-based solver is used.

S2S Radiation Heat Transfer Results
After calculation, 2D and 3D contours related to temperature, temperature gradient, velocity, pressure, and density are obtained. The contours show that the heat generated by the plates is transferred through radiation between the surfaces in the space around the pipe. This radiation heat transfer between the surfaces leads to an increase in the air temperature of the tube.

Julius Parisian –
Was it mentioned in the simulation if natural convection was considered in addition to the S2S radiation for heat transfer calculations?
MR CFD Support –
Yes, the description of the setup mentions air inside the boxes around the tube, suggesting that natural convection could contribute to the heat transfer. However, no explicit mention of considering natural convection in the calculations is made, so the simulation mainly focuses on S2S radiation heat transfer.
Sidney Schmitt –
I’ve noticed an incredible uniformity in the temperature distribution in the provided simulation results. Could you explain how the S2S model ensures this level of consistency despite the complex interactions between radiating surfaces?
MR CFD Support –
The S2S (Surface-to-Surface) radiation model is designed to calculate radiation exchange between gray-diffuse surfaces within an enclosure very effectively. The accuracy of the simulation is due to the careful calculation of view factors—geometric functions that account for surface size, separation distance, and orientation, which influence how heat is radiated between surfaces. In addition, by assuming that the surfaces are gray and diffuse (consistent emissivity and reflectivity), the S2S model simplifies the complex interactions to a more predictable and stable state, promoting uniform heat transfer and hence, a more uniform temperature distribution.

Ms. Shayna Grant IV –
Everything about the way the heat transfer is simulated with S2S method was clear, but I’m curious if with the provided settings, the distribution of temperature around the corners of the boxes seemed realistic?
MR CFD Support –
Thank you for your positive feedback. To address your question, yes, with the settings provided in this simulation, the temperature distribution around the corners should be evaluated realistically. The S2S radiation model considers the geometric factors such as size, separation distance, and orientation to calculate the radiation exchange accurately, including the effects at the corners. The results, which include temperature contours, help to visualize these distributions. If further detailed inspection is needed, adjustments to the mesh or simulation parameters could be made for enhanced precision.

Miss Stacy Jerde PhD –
Are the plates and the tube considered of the same material, or do they have different thermal properties in the S2S radiation heat transfer simulation?
MR CFD Support –
In the S2S radiation heat transfer simulation conducted via ANSYS Fluent, the plates and the tube could have distinct thermal properties. This typically includes differences in emissivity, material density, specific heat capacity, and thermal conductivity, key factors that impact the rate and efficiency of heat transfer. However, to precisely answer this, further information regarding the materials used for the plates and the tube in the specific simulation is required.
